Odo-Con 2019 Finds a New Ohio Record!

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!

The Citrine Forktail is about 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.

Blue corporal dragonfly - can you see it
What, you don’t see him?

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!

Hooked on Odes

This past weekend was the long-awaited Odo-Con, the dragonfly conference of the Ohio Odonata Society. This was my second year to attend, and I was glad that this time I would know more people and not feel like such a newbie. I’d convinced my friend Ryan to go along this year and was looking forward to seeing his reaction to being around so many other odonata afficionados.

The location for this year’s conference was the Oakwoods Nature Preserve in Findlay, Ohio. It was nice to have the conference in our corner of the state this time, although our weather forecast was not very good for the weekend — we were supposed to have scattered thunderstorms and overcast skies Friday and Saturday.

We spent Friday evening indoors listening to a variety of presentations on topics like the ethics of collecting insects, identification tips, and photography techniques. Whereas birders can report their birds to eBird without photos, our dragonfly survey requires photographic evidence of each species, making it very important to  know the best ways to get those photos. The photography panel discussion included Judy Semroc and my  friends Rick Nirschl and Jim McCormac, each with their own expertise and suggestions for the equipment and techniques that work best for them. It was a great discussion and I came away with some good notes.

Friday night after dark, they hung out sheets and lights to attract moths, and I enjoyed seeing some new moths and poking around in the woods with flashlights trying to find caterpillars.

Saturday morning was also filled with more interesting presentations and time for socializing. And, in a stroke of good fortune, the weather cooperated for our afternoon field trips after all. My trip was to a spot that sounds unappealing — the Hancock County dump. But this property has some amazing ponds and meadows, and we couldn’t even see (or smell) the actual landfill part of it while we were there.

And my gosh, were there lots of great odes there! Our group of about ten people was led by Linda Gilbert and Jim McCormac, and they showed us a grand time for about four hours, turning up about two dozen species of odes. One of the best finds of the day happened in the first 20 minutes of our outing, but we didn’t know what it was until the end of the afternoon when we pulled out my field guide and looked it up. It was a Mocha Emerald, a brand new species for me, and a very impressively-sized one too. We watched it flying over our heads for several minutes, until it finally landed on some vegetation along the path and we were able to creep up slowly and get some photos.

A little while later we made our way to the first pond, where we found lots of species flying. There were many pairs of Halloween Pennants “in tandem,” which is how we describe their mating position when the male is clasping the female behind her head. In the photo above they’ve already fertilized the eggs and he’s holding on to her while she dips her abdomen in the pond to deposit them. His goal is to make sure no other male interrupts her before she’s finished the job.

We found this female baskettail species (below) hanging in the meadow as she began releasing fertilized eggs from the end of her abdomen. We watched as the egg clusters got bigger and bigger, and finally she flew off over the adjacent pond and deposited them in the water. We can’t be positive about her species because we can’t see the terminal appendages with all those eggs covering them, but most likely this was a Common Baskettail (Epitheca cynosura).

We came to another pond that had just a narrow area of shoreline access, where our entire group couldn’t spread out at the same time. So our always-prepared leader went into the pond with a net to catch some specimens for us to examine on shore. I think he was having the most fun here, as the rest of us were getting eaten alive by mosquitoes in this particular area. But it was worth it, because he brought us some beautiful insects to see.

Jim is really in his element here, wading in the pond to net some bugs for us to examine.

For example, here’s a damselfly he netted, being held by our other leader, Linda Gilbert. This one is an Elegant Spreadwing (Lestes inaequalis). In case you’re wondering, all of the insects we netted today were released unharmed after only a couple minutes.

Spreadwings are a group of damselflies that are easy to distinguish from other damsels because of their habit of holding their wings partially outspread when perched. And many of them have beautiful metallic green coloration, like little winged jewels. I love them, even though many of them are frustratingly difficult to identify to the species level.

I’ll finish this installment with a few pics of an amorous pair of Stream Bluets that I photographed during a break between presentations at the Oakwoods Nature Preserve. First, the unsuspecting female just hanging out, minding her own business.

Next thing she knows, this guy grabs her by the back of her neck.

Not much she can do about it at this point, but it all seemed to work out, as seen below as they form the “heart” shape when she reaches her abdomen up to obtain a sperm packet from the male to fertilize her eggs. When they’re done with this part, she’ll oviposit into the vegetation in or near the water so their offspring can live in the water until they’re ready to emerge as these awesome winged creatures.

There’s much more to tell about our post-conference dragon hunting on Sunday, but I’ll save that for the next post. Suffice it to say that this was a fascinating weekend spent with naturalists and scientists, and I’m already looking forward to Odo-Con 2019. The only question is, how many more of my friends can I get hooked on odes before then?
