After my walk in the woods today, I stopped to admire the flower garden at my local metropark. It’s a beautiful garden of both natives and non-natives, and I was checking to see if there were any interesting insects hanging out there. My passion for native plants has turned me into a total bug geek, and I can’t resist looking beyond the simple beauty of the flowers to find the other hidden lives within their parts.
Since I’d been on a fitness walk, I only had my cell phone with me and so I started trying to take photos with it. But it’s terrible at macro shots. And so when I saw something new, I ran to the car for my real camera so I could document my cool discovery.
This is an ambush bug, a member of the assassin bug family. I believe this one is a jagged ambush bug (genus Phymata). This is the first ambush bug I’ve ever photographed, so I was very excited to discover him hiding in plain sight on top of a Black-eyed Susan flowerhead. As the name implies, they hunt by sitting in wait for a hapless victim to wander within reach of their lethal grasp.
After photographing his dorsal side, I slowly moved around to get a lateral view. Often when I’m shooting tiny subjects like this, I can’t fully see the details until I zoom in on the LCD screen on the back of the camera. And as I did that, I had to restrain myself from giggling out loud when I saw this adorable face:
I know, it might be adorable to me, but I wouldn’t want to be a small beetle trundling around those petals, I’ll tell you that. I mean, just look at those forelegs — they give you an indication of the reach he’s capable of. And little did I know then, but I was about to see one of these guys in action. Well, sort of.
I moved along, photographing other insects, and then came upon another great piece to the story of the jagged ambush bug. I found this second one with a recently-acquired victim! All I can tell is that it’s some kind of bee. As I took my photos, the bee seemed to still be moving slightly, so that’s why I figured I’d just missed the grab.
If you look closely at that last picture, you can see the bug’s proboscis stabbed into the bee’s abdomen. After he grabs his prey with those powerful legs, he injects poison that liquefies its insides. The insides are then sucked out through a rostrum, a straw-like structure inside the proboscis. Is that not cool or what?!
Aren’t we lucky these things are so small? With its powerful pincer legs, an ambush bug can easily take an insect up to ten times its size. Imagine a dog-sized ambush bug lurking in the shrubbery as you take your evening stroll…yikes!
Okay, that was a little bit unnerving, wasn’t it? Here’s a nice calming photo of the trail in the woods…take a deep breath…and forget all about ambush bugs. For now, at least. 😉
I had a rewarding experience today while doing my dragonfly monitoring at Wiregrass Lake. It was a beautiful morning and there were only a couple other people at the park, so there were few distractions as I was concentrating on counting odes and taking documentation photos.
About halfway around the lake, a guy with a fishing pole came past me and stepped out onto one of the little stone fishing platforms. They’re popular fishing spots because there aren’t many accessible areas of shoreline from which to cast a line. But they’re also preferred perching spots for certain dragonflies, so I always approach them slowly and hope to find something interesting there.
So when this guy stepped out onto the rocks, I admit to feeling a little twinge of irritation that he would have flushed any good bugs that might have been there. But I know the parks have to serve people with varied recreational interests, and his interest just happened to conflict with mine. I have to be accepting of that, I get it.
But here’s where things became interesting.
Just as I said a friendly hello to him, a pair of mating Common Green Darners landed on some floating vegetation in front of us and began ovipositing. I was very excited because I’d been trying to get some photos of those darn darners as they flew around the lake, so this was a perfect opportunity to get an easy shot. As I often do, I expressed my excitement to the person who happened to be nearest to me, the guy with his fishing line barely ten feet from my target insects. I admit that I was also telling him about them so he wouldn’t throw his line at them and scare them before I got my photo. My comment was ignored, or so I thought. He didn’t say anything as I shot several photos, and I thought he must just think I’m a weird bug dork. (And I am, I know.)
But then he started asking me questions about what they were doing. He wanted to know if they were laying eggs in the water. He wanted to know how long it would be before the eggs hatched, and how long dragonflies lived. I was overjoyed to find someone who actually wanted to hear this stuff, and so I dove in and gave him much more information than he’d bargained for. I told him about how green darners migrate like monarch butterflies. I explained about how their larvae emerge from their “shells” just like cicadas do. Each time I spouted another fact about their life history, he seemed eager to know more.
But finally I realized I would just go on for an hour if he didn’t stop me, and so I apologized for bombarding him with information and started to leave. But he actually thanked me and said “That was very interesting!” and that instantly became one of the best moments of my entire day.
It’s human nature to want other people to share our interests, isn’t it? I wrote about nonconformity and social acceptance in my last post, and I’m reminded of it again today. I’m used to being looked at as an oddity when I gush about my latest nature passion, whether it’s birds, dragonflies, or hoverflies. It doesn’t bother me much, because these things give me a deeper appreciation for the workings of the natural world, and make my life rich and rewarding. So I can deal with being looked at that way. But on those occasions like today, when a total stranger shows interest in something and lets me tell them about it, I’m overjoyed and feel like I’ve made an important contribution to that person’s connection to the natural world too.
As I walked away to continue my monitoring, I smiled to myself as I imagined that guy telling his wife about our encounter over dinner tonight. “Honey, would you pass the salad please? And by the way, did you know that dragonflies can live under water for years before they emerge as flying insects?” You never know, it could happen. And that’s exactly why I write this blog, to share what I learn about nature with the hope that you, my readers, will be excited enough about it to tell someone else. And if you do, I hope you’ll tell me about it. 🙂
It stands to reason that if you want to see things that are out in the dark, you need to become a creature of the night as well. And that’s exactly what I did this past weekend.
You’ve certainly heard of events celebrating birds and butterflies, but you may not have heard of Mothapalooza. It’s an event held in southern Ohio every other year, and the main activity at the weekend affair is gathering at lighted sheets in the middle of the night to look at moths. This was my first time to experience it, and I loved the geekiness of it all, and the chance to see so many stunning moths. The lodge at Shawnee State Park is the headquarters, and that’s where the talks and meals take place. Many attendees stay in the lodge and more fill the two dozen cabins behind the lodge. I stayed in a cabin with my friends George, Angie, and Jackie.
Most people don’t give moths a second thought unless they’re swatting them away from the porch light to keep them out of the house. Did you know that many moths are pollinators? Yep, butterflies and bees do this important work during the day, while moths work the night shift. It’s so cool to realize that the ecosystem doesn’t sleep when we do; there are critical interactions happening all night long!
I’ve tried setting up my own light system to attract moths here at home, but have had limited success with that so far. (I think it’s partly because I hesitate to use a bright enough light for fear my neighbors will complain about the crazy bug lady.)
As you can see from this photo, some of the moths are huge, but there are also micromoths that are hard to see without a hand lens. I focused on photographing the larger ones this time, but maybe next time I’ll be calmed down enough to try the smaller ones. When I walked up to the first mothing sheet on Friday night, I was blown away by the beauty and variety of insects that had gathered there. I hope I can convey some of that excitement to you by sharing a few photos.
The sizes of these moths range from about 6 inches (wingspan) for the big silk moths, down to less than a tenth of an inch for the micromoths. I’d say most of the moths I photographed fall in the range of about 1-3″ wingspans.
So here’s how Mothapalooza works:
Each evening the organizers set up lights and sheets around the lodge area, and we could go visit the sheets at our leisure, walking through the night with flashlights to get from one station to the next. I joked that I felt like I was going trick-or-treating as we walked through the cabin area in the dark, visiting the moth sheets of other people to see what they’d attracted. They also had a half dozen remote locations set up, and they offered a shuttle service to take us to those. Mothing was scheduled from 10 pm to 2 am each night, but I know quite a few people who stayed up much later than 2:00. I learned that the moths tend to come to the lights at different times, so there are apparently some that you won’t see unless you’re willing to check the lights all through the night. I barely made it until 1:00 the first night and 2:00 the second night, despite being a night owl in my normal life. It wouldn’t be so bad if you could sleep until noon the next day, but there’s so much cool wildlife to see down there that we all felt we should be awake and exploring for as many hours as possible. (Moths by night, dragonflies and butterflies by day!)
Black-waved Flannel Moth
Face view of same moth
A couple years ago I got my first look at the spectacular caterpillar of the Pandorus Sphinx (Eumorpha pandorus), and this weekend I saw the adult form of the same animal. First the caterpillar:
And then the adult moth:
Is that not a marvelous creature?! The host plants for the caterpillar are grape and Virginia creeper, and when my friend and I found the caterpillar, it was indeed feeding on grape leaves. I was so enchanted by that caterpillar that I can’t resist scanning every grape leaf I pass on my walks, just in case I can find another one. And this moth is quite substantial, so when one of them crashes into your head, you definitely notice it.
I’m going to put a lot more photos on my blog’s Facebook page instead of posting them all here. So if you’re on Facebook, you can “Like” and “Follow” my page to see more cool photos than you can see here. (Here’s the link.)
I’m so glad I had this exciting experience! I got a change of scenery, met new friends, learned more about the natural world, and was inspired to share it with you here. I hope this might motivate some of you to hang a sheet outside and point a light at it and see what shows up. You just never know what surprises are out there in your own backyard!
Here’s a brief video to show what it’s like at a mothing station:
I took a couple extra days after Mothapalooza to drive around the southern counties of Ohio looking for dragonflies, so I’m still trying to get rested and get myself back on a normal schedule. I’ll have some fun dragon stories and photos to share next time, so I hope you’ll come back. 🙂
Dragonflies are fierce predators of other insects, seemingly invincible as they zip around ponds and meadows at warp speed. But they themselves fall prey to birds and even other dragonflies, in the dog-eat-dog (dragon-eat-dragon?) insect world.
One predator you might not expect to feast on something as fast as a dragonfly might be a spider. But the spider’s deathly weapon — the web — can definitely ruin a dragonfly’s day.
My friends Hal and Ginny woke up one morning on their recent vacation to find a young Calico Pennant ensnared in the sticky strands of a web outside their cabin in northern Michigan. They immediately jumped into action to try to free the little guy. Hal wrote an account of their efforts for our Wild Ones Oak Openings Region newsletter (he’s our chapter President), and he has given me permission to reprint an excerpt of his article for you. So here it is:
During the night a spider had constructed a web of fascinating geometry. Normally the sparkling dew-laden strands would have caught my attention first. But, not this time! A large dragonfly was solidly entangled in the sticky threads. It must have been there a long time as it had given up and appeared to have gone to dragonfly heaven. I was surprised the web’s eight-legged architect hadn’t already wrapped this prize up for a later feast.
Not seeing the spider, I decided to get a better look at the prey. I pushed my finger to move the colorful insect and SURPRISE! Two of its legs not entangled wiggled and grasped my forefinger. It was alive. Now what do I do? I felt bad for this fascinating creature. But I was witnessing the natural food web in action, up close and personal.
I again looked for the arachnid whose livelihood I was messing with. Didn’t see it. So, I pulled a little and the dragonfly clutched more strongly. It tried flapping its wings to escape but the threads held. I pulled a little more and one of the wings came free of the web. The dragonfly held tighter on to me. Pulling some more, two more wings came free. Another easy tug freed the final wing, but four legs were still tangled up. Putting my fingers behind its wings prevented them from being recaptured while I pulled at the remaining silk chained to the legs.
Now, completely free from the web, the dragonfly sat on the deck railing. It tried again to fly but couldn’t. I saw a piece of silk holding the right fore and hind wings together. By now, Ginny had heard me. She brought some flat toothpicks and took pictures. There was enough space between the wings for me to insert the toothpick and gently extract the silk.
Now testing its freed wings, the dragon rose into the air a little, but quickly landed back on the railing. Noticing a gob of web residue holding several of the legs together, some more toothpick work was in order. Using two toothpicks I was able to separate most of the constraint. The insect rose a few inches above the wooden railing. Again, it quickly returned but this time to my finger. This time it took a little while to find one last vestige of the spider’s handywork wrapped around the right front leg. The silk didn’t let go easily. But finally, it did release.
That little creature must have been exhausted from its brush with death. Slowly it climbed farther up on my finger and rested for a few moments. As we looked at each other, I wondered how I appeared to it. Ever so slowly it rose vertically into the air, hovered for a second, flew a couple of feet to my left, turned 180 degrees, and flew to the right, then returned to hover in front of me for what seemed like a breathtaking minute. Then it was gone.
Knowing what kind people Hal and Ginny are, I’m not the least bit surprised that they wanted to help this beautiful creature. I’m very impressed with how they delicately disentangled it and gave it a chance to live out its life. Thanks Hal and Ginny, for sharing this story with all of us. I bet that Calico Pennant has already found a girlfriend and told her how you saved him so just he could make babies with her!
I had planned to write about my visit to Lynx Prairie after Odo-Con, but time is getting away from me and it seems every day brings something else new and exciting that I want to share. I’ve got a huge backlog of things to write about — and perhaps I’ll still write about Lynx Prairie later — but today I want to tell you about a recent day that was very special to me.
I’ve been on the board of Toledo Naturalists’ Association for about a year and a half now, and have often felt that I should step up and serve as a leader for one of our many field trips. But I was nervous about not having enough experience or knowledge to be a “good” leader, so I didn’t speak up and volunteer. At our board meeting last August, I was asked to lead the annual dragonfly field trip this year and, caught off guard without a good excuse, I agreed to do it. In the ensuing nine months, whenever I thought about it, I got a little bit nervous. Would anyone show up? Would I show my ignorance when I couldn’t answer all their questions? But I determined to be as prepared as I could, and to bring my natural enthusiasm and hope that would be enough.
On the designated Saturday I arrived at Wiregrass Metropark to find a half dozen people already there waiting for me, and we ended up with 19 people on the walk. I was so pleased at the good turnout, and happy to have many friends there to support me on my first leading experience. Those friendly faces eased my nerves quite a bit, and I started off the morning by giving the group some basic facts about dragon- and damselflies and showing them the field guides I use. I had obtained a supply of the excellent dragonfly field guide pamphlets from the Ohio Division of Wildlife, and handed those out to people who wanted them.
The plan was to spend two hours walking the 0.6-mile loop trail around the lake looking for odes and anything else interesting we could find. I was worried about the weather, because it was mostly cloudy, which isn’t optimal for finding flying dragonflies. As ectothermic insects, they can’t generate their own body heat and must rely on the sun to give them the energy to fly. I’m always amazed at how quickly they respond to the sun and clouds on a day when the clouds are moving a lot. I can be watching dozens of them flying over a pond in the sunlight, and then a big cloud covers the sun and they all disappear almost instantly. Then in a few minutes when the cloud moves past the sun, the bugs start flying again pretty quickly too. It’s really fascinating to see.
Our walk started out a bit slow, but very shortly things picked up and we had a grand time with good looks at more than a dozen species. I knew people would love seeing the flashier dragonflies, like Twelve-spotted Skimmers (below) and Calico Pennants (above).
But I especially enjoyed showing them the tiny little damselflies that flit around in the grasses, like this Double-striped Bluet. I explained that you have to train your eyes to watch for the movement of “little blue needles” in the grass. It was fun to see their joy when they finally locked in on one of them and saw how small they are. This one, for example, is only about an inch long:
And this Emerald Spreadwing was a real crowd pleaser too:
Here’s a pic of the baskettail we were looking at in the photo above:
This experience was gratifying for me on two levels: First, because everyone seemed to have a really good time, and, second, because it helped me overcome my fear of putting myself out there as a leader. I learned that I don’t have to have all the answers, and that enthusiasm can more than make up for any lack of experience. And I’ve got enthusiasm in spades when it comes to odes.
I seem to find a way to bring dragonflies into just about any conversation these days. Which is how I ended up volunteering to start an odonata monitoring program for Metroparks Toledo. Back in the very early spring, I was meeting with their research supervisor to talk about my work in their raptor monitoring program, and I happened to mention my love of dragonflies. She asked if I’d be interested in helping them track the odonate populations at one of our local parks. And I instantly said, “Yes, of course!”
The park happens to be Wiregrass Lake, the same one where our field trip took place. Wiregrass is a newer Metropark, having only opened to the public in 2015. Prior to the park opening, my friend Rick Nirschl made frequent visits to the site to study dragonflies, and he provided Metroparks Toledo with a great deal of initial data about the odonates on the property, as well as suggestions for managing it to protect their habitats. Largely due to his efforts, Wiregrass has become known as the Metropark with the largest number of odonate species. Since the park’s opening, though, there has seemed to be a decline in the variety of species as well as overall numbers. And that’s what prompted this effort to gather more data.
Over the next few weeks, we discussed what the park system wanted to achieve and then we set up a monitoring protocol loosely modeled on those used to monitor butterflies. We divided the park into transects, and once each ten days I go there and count the number of each species present. I’ve found that counting dragonflies is much more difficult than counting birds or even butterflies, but I’m doing my best to get an accurate representation of the populations.
Two years after moving to Toledo, I continue to view our Metroparks as one of the best parts of my life here. There are endless opportunities to volunteer in the park system and I feel like a valued member of the community when I participate. Just this morning I spent two hours with other volunteers (from my Wild Ones Oak Openings chapter) helping remove invasive honeysuckle and buckthorn at Wildwood Metropark. It was 90 degrees in the morning, and it was hard work, but the results were clearly visible when we were done. And that felt good.
I’ve just returned home from this year’s Ohio Dragonfly Conference — also known as Odo-Con (Odonata Conference). This was my third year to attend, and it just keeps getting better. The conference moves around the state each year, allowing us to get a taste of the odes outside our home areas. The 2017 conference was in Ashtabula County, in the northeastern quadrant of the state. Last year’s was in Findlay (Hancock County), here in the northwestern corner of the state. This year’s Odo-Con was held in Gallia County in southern Ohio, down in a tiny little place called Rio Grande. I just discovered that the population of the village of Rio Grande was 830 in the last census, so I wasn’t exaggerating when I used the word tiny. But even so, they have a university there, and that’s where we held our conference.
Because they’re ectothermic, weather is a big factor in whether or not the odonata will be flying on any given day (they need the warmth of the sun to generate enough body heat). So I was discouraged when I arrived in the area late Friday afternoon as thunderstorms were passing through. I’d hoped to do a bit of dragon hunting before the evening presentations started at 6:00, but it just wasn’t meant to be. But the evening went well; I learned a lot and had a great time reconnecting with friends from around the state, and meeting some new friends too.
Since the weather hadn’t cooperated on Friday evening, I decided to skip the morning presentations and go out hunting on my own Saturday morning. The ode season has been very slow in coming to northwest Ohio because of our cool and wet spring, so driving four hours south felt like going on an exotic vacation and I was eager to find some interesting bugs.
Unfortunately, I didn’t find much that morning because it was still pretty cloudy. But the universe threw us a bone in the afternoon, allowing the sun to shine for our field trip groups as we explored Gallia and Jackson counties. My group first visited a small city park, which didn’t seem too exciting at first, but that’s where I saw my first lifer, a Citrine Forktail. I didn’t get a good photo of it, but saw another one later in the day, and that’s where I got this decent shot. Keep in mind, this dude is less than an inch long!
And as I was reading about this species, I learned something fascinating: in the Azores, Citrine Forktails are parthenogenetic, meaning that females lay unfertilized eggs that become new females. Ahem, no males needed. Dennis Paulson’s book says that this is the only species of odonate known to reproduce this way. So I wonder if that means there are no males in the Azores, or if they’re just redundant. (There are so many possible jokes I could make here, but I’ll exercise restraint. I’m giggling though.)
Things were starting to get exciting when we found a Great Blue Skimmer perched on a branch hanging over a small stream. We took turns holding back foliage so we could all get a look at it, and I managed to get a good enough shot to document it. It’s too bad he wasn’t turned more toward the camera so you could see his cool white face with blue eyes.
Soon we moved on to Cooper Hollow Wildlife Area, where we spent several hours visiting a few ponds. The first pond was absolutely loaded with the flying monsters, and we had a blast. It was so overwhelming that I found myself feeling like I didn’t know what to photograph first. I’d be shooting a Spangled Skimmer right in front of me, and someone would say, “Hey, there’s a darner flying!” and I’d want to try and shoot that one too. At the same time there would be clubtails landing on the ground all around my feet, and those usually require photos from two or three angles, so they’re a challenge. Here’s a photo of the pond — the electrical lines were emitting a constant crackling/buzzing sound which was a bit unnerving, but still worth it for chance to see so many dragons zipping around us.
The Ohio Dragonfly Survey requires either a photo or an actual insect specimen to document every sighting. That makes it quite a bit harder than submitting an eBird report, on which you can report birds without photos (you can even report birds that you’ve only heard and not seen, if you’re certain of the species). This is the third and final year of the new survey, and we’re busy searching the records to see which counties don’t have records of certain species, and trying to fill them in if we can. The results of the three-year survey will be published in book form, and I know quite a few people who will be anxious to get their hands on it. (By the way, if you take pictures of dragonflies or damselflies and would like to contribute your sightings to the Ohio Dragonfly Survey, go here to see how easy it is.)
I saw about 20 species just at this pond, and overall we saw more than 40 species during the conference. (Plus, there are some clubtails that we’ll probably never be able to confirm down to species level.) Not too bad for a few hours of field time! Our state survey coordinator, MaLisa Spring, was my field trip leader, and she found a new species for Ohio right at this pond. It’s being discussed by the experts now, but what was thought to be a weirdly-uncolored Banded Pennant (Celithemis fasciata) has likely turned out to be a first state record for Double-ringed Pennant (Celithemis verna). Very exciting! (If you’d like to see the photo and the ensuing discussion about it, go to iNaturalist, here.)
I photographed what I thought was a Slaty Skimmer at this pond, but now there’s a chance this is another one of the Double-ringed Pennants. It may not be possible to tell for sure because I only got this one angle documented, but the discussion is continuing on iNaturalist.
That’s some good stuff right there. I had such fun on this trip. Nature people are some of the most interesting people you’ll ever run across, and I learn something from every person I interact with at these events. I’m excited to be leading my first dragonfly field trip here in Toledo this Saturday (for Toledo Naturalists Association), and I hope to get some more local people enthused about contributing to our state dragonfly records.
On Sunday morning I decided to take the very long way back to Toledo, stopping along the way to hunt for more cool insects. I’ve got another post coming about a special place I stopped later in the day, but here’s what I found first thing Sunday morning.
This is a state endangered species, the Blue Corporal. Ohio is at the far northern boundary of its range, and we were hoping to document it this weekend. It was discovered by another field trip group on Saturday, so I knew the general location to begin my search on Sunday morning. I drove sooo far out a narrow gravel road that I lost cell reception and started to feel a bit nervous. As I got to the small lake that was my destination, I passed two guys sitting beside the road in a pickup truck. I started to think it might not be such a good idea for me to be way out there alone, and was wondering if I should just turn around. So I was extremely relieved to find another ode hunter already down at the parking lot on this dead end road. Not only did that make me feel more safe, but he had just seen the Blue Corporal and took me on a walk down a muddy road and pointed to the trunk of an evergreen tree and said, “There it is, just above the base of that branch that has been cut off….about a foot to the left.” And indeed, there it was, another lifer!
I took a few documentation photos but didn’t want to get too close and risk scaring it away, because I knew there would likely be other people coming to see it in the next couple of hours. Since I had many hours of driving ahead of me, I left right after seeing this bug, and just a half mile up the road I came across a couple who appeared to be lost and I knew right away what they were looking for — I gave them directions and headed off, winding my way to the west through the many small towns in southern Ohio.
Come back for some stories about the rest of this day’s adventures soon!
Dragon- and damselflies don’t often perch on photogenic flower heads, so when I found this one yesterday I was pleased. Of course it’s not a flower, but close enough. This is a female emerald spreadwing damselfly (Lestes dryas), clutching the seed capsule on a stem of seedbox (Ludwigia alternifolia). I’m calling it a two-fer because it’s an ode on a native plant, two awesome things for the price of one!
I discovered seedbox last fall while helping to collect seeds for my Wild Ones chapter, and instantly fell in love with its square seed capsules. They’re filled with tiny little seeds that rattle when shaken. Each seed capsule has a hole in the top, presumably so the seeds can fall out when the plant is blown by the wind or otherwise jostled. This plant has lovely yellow blooms in the summer, but they aren’t nearly as interesting as these little brown boxes, if you ask me. 🙂
I might be in the early stages of a love affair…with beetles. A sort of beetle-mania, so to speak. I was aware that there are more species of beetles than plants on our planet, but hadn’t paid any special attention to this group other than occasionally admiring a new one I discovered. But after a couple recent encounters, I’m finding myself growing interested in further study of this very cool group of insects. And since dragonfly season is taking forever to get here, I might as well use this time to get better acquainted with the insects that are already active.
Beetles are in the order Coleoptera, which comes from the Greek words koleos which means sheath (or shield), and ptera which means wings. As this name indicates, they have a hardened pair of forewings called elytra that protect the softer hindwings below.
You may have noticed the common beetle flight style while watching ladybugs; the elytra are lifted up to allow the softer wings below to open. It makes them appear to be somehow handicapped, as if they can’t manage to get those cumbersome appendages out of the way.
It seems that wouldn’t be the most efficient way to fly, but they seem to do just fine. (In fact, I read a study that found that the elytra do provide extra lift in flight, but they reduce aerodynamic efficiency.)
A few days ago I met the pigweed flea beetle; actually I met quite a few of them. I was enjoying a leisurely walk on a quiet trail in one of the less-traveled areas of Magee Marsh Wildlife Area. A half mile from my spot there were throngs of birders jostling for views of a Connecticut warbler, but I was in blissful peace, crouched on the ground watching beetles go about their business.
This particular one taught me something interesting. I watched him (her?) repeatedly open and close the elytra before finally achieving liftoff. I wonder about the purpose of the opening and closing of the elytra so many times; it could be part of a mating display or serve some other function.
Just a few days after being enchanted with the pigweed flea beetle’s display, I’ve met another beetle who taught me more cool stuff. This is the bumble flower beetle (Euphoria inda). Whereas the pigweed flea beetle was about a quarter inch long, this one was much bigger, more than a half inch long. (A quarter inch is significant in the insect world!)
As I was researching this species, I came across an article that claims this one is unique among beetles because he doesn’t raise the elytra when he flies. I haven’t seen reference to this claim to fame anywhere else, but if it’s true, it’s just one more reason to enjoy meeting this magnificent furry creature.
And before you scroll too far, go back and check out those awesome lamellate antennae! Beetles have some of the most interesting antennae I’ve yet come across in my insect studies. I often remember this guy, the big blister beetle I found on my front sidewalk a couple years ago. He’s got those impressive segmented (moniliform) and weirdly-kinked antennae. And his elytra are partially wrapped around his abdomen, in contrast to those of the species above.
Beetles come in all shapes, sizes, and colors, and I look forward to a summer of meeting many more of them and learning more about their fascinating lives!
Yes, you read that right — I said, “Dandelion Delight,” alright. Many people despise these little yellow flowers that pop up in lawns in early spring, and do everything they can to eradicate them. In fact, there may be no more-hated flower than the hapless dandelion.
You may be thinking, “Hey, aren’t you all about native plants now? What gives?” It’s true, the common dandelion (Taraxacumofficinale) isn’t native to North America, and I sure wouldn’t advise you to plant it on purpose. But it’s here and it’s widespread, and it’s not going anywhere anytime soon. But there’s a silver lining to this dilemma, and it’s the fact that dandelions are sometimes useful to early spring pollinators.
For example, right now there are very few native flowers blooming in my part of Ohio. And yet some of the pollinators have already emerged or migrated back. Luckily for these early bird insects, dandelions are a plentiful food source to get them through until more of our native flowers are blooming. The other day I went to a local nature preserve that has a thriving population of dandelions, because I wanted to show you some of the pollinators that were feeding on them.
First was the black-shouldered drone fly shown above. Then I found one of my favorites, a hoverfly. I believe this may be the American hoverfly (and I hope to confirm that when my new field guide arrives very soon!).
Butterflies may not be as efficient at pollinating as bees and flies, but they still make a valuable contribution to this essential step in botanical reproduction. Small amounts of pollen can attach to their wings or other body parts as they feed on nectar, thus allowing them to inadvertently carry that pollen to other flowers. On this day I saw many red admirals and American ladies feeding on the pretty yellow dandelion blooms.
And check out this greater bee fly with his long rigid proboscis. Unlike a butterfly, this fly can’t retract his “tongue.” That seems like it would be cumbersome, but he apparently makes it work.
His lovely wing pattern at first tricked me into thinking he was a tiger bee fly (which I wrote about last summer), but I quickly realized he was different. In fact, I had only seen my first of this species a couple days before, when I visited Goll Woods to photograph wildflowers.
I found a nice article about greater bee flies by Eric Eaton, so if you’d like to read more about them, I suggest you go to Eric’s blog, here.
So I hope this will give you pause the next time you’re considering yanking dandelions from your lawn, or even worse, pouring toxic chemicals on them. If we can learn to see them as beneficial to the ecosystem, and even — gasp! — enjoy their beauty, perhaps we can eventually learn to live in harmony with the rest of the life on this amazing planet.
On the morning of March 12, the ship anchored off the coast of Isabela Island near Elizabeth Bay. We piled into the zodiacs in groups of about 15 people, and headed off to explore the beautiful and peaceful mangrove lagoon.
Almost as soon as we entered the cove, we found a lone Galápagos penguin resting on a rock. He lay there calmly as our boat idled 20 feet away, allowing us to take some nice photos before moving on into the lagoon. These are the only penguins in the northern hemisphere, and are endemic to the Galápagos. The Galapágos Conservation Trust says this about their current conservation status: “In 1982, there was a particularly strong El Niño event that caused 77% of the population to die of starvation and the population has been recovering ever since. The current population is estimated to be just 2,000 birds.”
We soon saw a sea turtle napping in the shade, using the mangrove branches to keep himself afloat.
Another one popped up to say hello.
I absolutely love turtle heads, don’t you? They look like toothless old men, but in a cute way.
In this lagoon we also got our first and only fleeting looks at golden rays. Unfortunately I didn’t get any photos of them before they were gone. I was also excited to see quite a few dragonflies zipping around above us. I’d not held out much hope of finding any dragonflies on this trip, so it was a big thrill. Dragonflies need fresh or brackish water, and I knew that most of our trip would be spent on salt water. But I believe the lagoon is brackish water, so that’s why there were dragonflies there. I was trying so hard to get a photo of one of them, and the boat driver tried to get me close to one, but I just couldn’t get the photo as the zodiac bobbed on the water. Talk about frustration! But all wasn’t lost in the ode department, because I managed to get a photo of one dragonfly on North Seymour island later in the week.
Small groups of penguins entertained us as they swam around us. We found two sea lions tucked up in the mangrove trees enjoying naps in the shade. I was a little bit irritated that our guide nudged the boat into their little sheltered hideaway to allow people to take pictures of them. Most times the guides were very good about keeping a decent distance from the wildlife, but this time I felt they went too far in invading the space of the sea lions, so I was glad when we finally backed out of the little inlet and moved on. I didn’t take any pictures of them because I felt bad that we were there.
This striated heron was lurking in the shelter of the mangroves too. I’ll have more to say about this species in a future post.
As we began our return trip out of the lagoon, a great blue heron flew in and landed in a mangrove tree, and I had that weird feeling that I often get when birding in a far-off location and seeing a bird that I see in Ohio. It’s like seeing a friend from home and saying, “Hey, I know you!”
There was one more treat to discover before we went back to the ship, and boy, was it great! This flightless cormorant was sunning itself on a rock as we emerged from the lagoon, and it made for such a gorgeous photo with the backdrop of the brilliant turquoise water.
The flightless cormorant is another endemic species in the Galápagos, so this was high on my bucket list of species I wanted to see. We only saw a few of them on the entire trip, and this was the closest we got to one. This photo is perfect for highlighting his stunted wings, which are the obvious reason that he’s flightless. He doesn’t even use those wings to propel himself through the water when fishing, instead relying on his powerful feet for propulsion. Because his wings don’t produce much oil, he can’t waterproof his feathers and has to spread the wings to dry in the sun after he’s done diving.
Okay, that’s three posts on the Galápagos trip, and I haven’t even mentioned Darwin’s finches yet. Stay tuned!
