Dragonfly
Society of the Americas Annual Meeting
June 19-21, 2009, Sullivan, Missouri
& pre-meeting and post-meeting excursions
Tuesday, June 16: There were two pre-meeting trip options available
before the DSA annual meeting in Sullivan, Missouri. One was based in
the town of Columbia, a couple hours west of St. Louis where I would be
landing. The other was in the far southwestern corner of the State in
Lamar, a good 6 hour drive from St. Louis. Guess which one I chose.
There were actually more species I needed on the Columbia trip list versus
the list for Lamar, but most of those we could encounter during the meeting
itself. Still up to a couple of days before getting on the plane (from
New York to Atlanta to St Louis) I hadn't made up my mind which one to
attend. But on the DSA webpage for the meeting there was a scan of an
odd spiketail. Maybe a new species or just a prairie variation of an Arrowhead
Spiketail, Cordulegaster obliqua. Instead of small yellow arrowheads
on top of the abdomen it had large rectangular markings. Being a sucker
for pictures, I just had to see this one despite one grueling travel day.
When I arrived at the motel in Lamar, Tim Vogt had a living pair waiting,
having caught them a couple of days previously.
Wednesday, June 17: Led by Tim, we were a small group: Nick and
Ailsa Donnelly, Mike Blust, Bryan Pfeiffer, Erik Pilgrim, and myself.
We looked for more Cordulegasters, following a small stream along
the edge of Prairie State Park. A few Regal Fritillary butterflies floated
on the breeze. Bryan caught a young male spiketail, and later a female
was caught. We came to a pond, where some common skimmers were flying,
mostly Spangled, Libellula cyanea and Widow Skimmers,
Libellula luctuosa. We found a handful of male Stillwater Clubtails,
Arigomphus lentulus perching along the pond edges. No females were
seen, the first of many targets missed.
Our next stop was a parcel of prairie called Cook Meadows. In the rising
heat we found another spiketail, which Bryan and Mike photographed. It
was likely the first time this particular form had been photographed in
the field. After they were done I moved in with the net but it had enough
of posing and took off before I was ready to swing.
We tried a couple of more spots and saw a few more species like Comet
Darner, Anax longipes and Mocha Emerald, Somatochlora
linearis. I got to step onto Kansas soil for the first time. At the
end of the day we stopped to turn the cars around to head back to Lamar
when we noticed a few dragonflies flying around. We managed to net a few
which turned out to be Slender Baskettails, Epitheca costalis.
We saw another Comet Darner, then a River Cruiser, Macromia of
some sort. Tim netted a Sulphur-tipped Clubtail, Gomphus militaris
that just happened to fly by, the only one I saw on the trip. I spotted
a Black-shouldered Spinyleg, Dromogomphus spinosus, and
Bryan braved poison ivy to reach for a Banded Pennant, Celithemis
fasciata. It was a pleasant way to end the day, unexpected variety
on a random stretch of road.
Thursday, June 18: Our plan was to revisit Cook Meadows in the
morning for more spiketails. Tim needed more individuals for DNA work
on them. Then we would head three hours east, stop at a fen in Mark Twain
National Forest before heading to the meeting in Sullivan.
I spotted a spiketail the moment I reached the stream. I followed until
it landed and netted it. A little ways down the stream I caught another
male gaining a little redemption for missing the one the day before. Later
I spotted a third, but it had just emerged and was very teneral. Although
it would have been just as useful for DNA, I decided to let it go unmolested.
Tim caught another female so three from the site should be sufficient.
Then we convoyed east arriving at Kaintuck Hollow in mid-afternoon. Tim
warned us there might be biting flies in the fen but they weren't bad
at all. But it was hot and coupled with the humidity in the fen it was
hard not to just stand in the shade. There weren't many species found,
Gray Petaltail, Tachopteryx thoreyi and Seepage Dancer,
Argia bipunctulata were the most common. There were handful of
skimmers and a few Springwater Dancers, Argia plana of the
blue variety. I was hoping to find clubtails so I worked the dryer ground
and I found a single female Westfall's Snaketail, Ophiogomphus
westfalli. I had collected only a male of the species a couple of
years ago in Arkansas so this was on my list and a fortunate find.
Friday, June 19: Field trips began at 8AM heading mostly for the
Meramec and Bourbeuse Rivers. The organizers provided quite a list of
species for the two rivers but nothing was guaranteed. I was particularly
interested in the pond clubtails, Arigomphus for which I need females,
a couple rare for the region clubtails, Gomphus, and Gilded
River Cruiser, Macromia pacifica.
I joined the Bourbeuse River group led by Jane Walker and Joe Smentowski.
The first clubtail we found was a Common Sanddragon, Progomphus
obscurus. Further down river we started seeing a clubtail with lots
of yellow on the abdomen which turned out to be Pronghorn Clubtail,
Gomphus graslinellus. We also picked up Ozark Clubtail,
Gomphus ozarkensis a large dull colored species and the tiny
Interior Least Clubtail, Stylogomphus sigmastylus. I saw a
River Cruiser. It did not have a lot of yellow on the abdomen so it probably
was a Swift River Cruiser, Macromia illinoiensis. As the
group scattered up and down the stream, Joe was trying hard to keep tabs
on everyone's whereabouts during the stop. I was told he was a retired
science teacher and he sure seemed to be treating us like students on
a field trip. I was amused at first but after a little while it got annoying.
We tried a couple of crossings further downstream but the river was swollen
and difficult to access. We returned to a spot upstream that looked good
when we stumbled upon it earlier, and spent the rest of the afternoon
there. We found a couple of male Westfall's Snaketails, and late in the
day I caught a male Rapids Clubtail, Gomphus quadricolor
but I did not get or see anything on my list.
Saturday, June 20: The business meeting indoors. The talks were
fine although I was nodding off a bit in the warm room. It's usually tempting
to skip out on the slide shows but the meager results of the day before
were not encouraging. Rain, swollen rivers, now heat. I've been here before.
The arranged buffet banquet in the town of Cuba was pleasant enough. I
ate plenty. Near the end Joe stood up and reminded everyone to gas up
before we went on the next day's field trips because on the previous day
we irked him by stopping for gas along the way to the Bourbeuse. (Helps
if the leader tells us beforehand how far we had to go). Dennis Paulson
stood up and asked if we should all go to the bathroom first, getting
a good laugh from the room.
Sunday, June 21: Two trips were planned. One to see Hine's Emerald,
Somatochlora hineana and a second trip back to Kaintuck Hollow fen.
If I wasn't working on the book I probably would have tried to see the
emerald, a species I have not seen. But being listed as a federally endangered
species (which research has shown it shouldn't be) there wouldn't be any
netting and I'm not equipped for field photography. It also threatened
to resemble another school field trip. But I weighed the certainty of
seeing the emerald versus the shrinking possibility of finding something
I needed at Kaintuck. It would be earlier in the day than my last visit
to the fen so maybe there might be something different.
There were a few more species found. The most intriguing was a female
emerald that we waited for but could not relocate. After driving around
a bit we located a couple of ponds. I was hoping for females of Comet
Darner, Spatterdock Darner, Rhionaeschna mutata and Unicorn
Clubtail, Arigomphus villosipes. We saw males of all these
species. I saw what I think was a female Unicorn Clubtail perched along
the creek but watched it disappear winging down the stream.
I said my goodbyes to the group and headed southeast to spend the night
in the town of Farmington. Tim Vogt recommended a site in Madison Co.
for Gilded River Cruiser and both he and Ken Tennessen encouraged me to
get to the creek early in the morning. So far I had only gotten the odd
spiketails and the female Westfall's Snaketail so I felt like I needed
the river cruiser to make my trip a success.
Monday, June 22: At was at Marble Creek in the Mark Twain National
Forest at 7AM and saw river cruisers flying along the stream above a dam.
The water was deep on the parking lot side of the creek so I couldn't
wade in. I perched myself on the rock and tried to catch the dragonflies
as they came by. They flew a fairly consistent path, coming down along
my side of the stream until they came to some overhanging branches then
crossed to the far side. Still they were at the edge of the range of my
swing and when I finally got the net on one I knocked it into the water.
I tried to scoop it out but the current carried it away from me. As I
watched in frustration, a fish rose and pulled the dragonfly under.
Annoyed at the overhanging branch I thought I could possibly pull it closer
to shore and perhaps the cruisers would alter their path to follow along.
There was a submerged rock that I thought I could step on but it turned
out all the large stones were as slippery as ice. With the wrong shoes
I slid off the rock and found myself chest deep in water. Well that didn't
work. At least my camera was sitting dry on the bank.
I needed to get to the other side of the stream and I finally thought
to cross at the top of the dam. On the far side the sun was better, the
water shallower and gravel bottomed. I had a few better swings but the
cruisers were noticeably faster now that they had warmed up. My right
handed swing would often make me swing at them from the front and they
evaded me with ease. By 7:45 they were gone.
I tried along the shoreline and flushed up some Orange Shadowdragons,
Neurocordulia xanthosoma. I followed a powerline cut up to some
fields but didn't find where the cruisers were hiding. The temperature
rose to the high 90's. I took a nap, then tried again in the afternoon
hoping the cruisers would fly again. I outlasted a number of bathers seeking
relief from the heat and had the stream all to myself at 7PM. The sun
dipped below the trees and I headed back to the motel without seeing any
more river cruisers.
Tuesday, June 23: With my flight scheduled to leave at 1:30PM,
the morning would be my last chance to get Gilded River Cruiser. I got
up at 3:45AM, was on the road at 4:30 and arrived at the stream an hour
later. Although the sun would not rise for another 10 minutes I saw some
river cruisers. Flying with them were a couple of Dragonhunters,
Hagenius brevistylus and an Orange Shadowdragon or two. I quickly
crossed the dam and found a good rock that they cruisers seemed to fly
consistently close to. I pancaked my net onto one going by. Fishing it
out of the wet net, I was surprised to find it was an Illinois River Cruiser.
But I had clearly seen dragonflies with more yellow on the abdomen so
I got back on the rock and waited for the next one.
The wet net landed with a plop and this time it was a male Gilded. I felt
more relieved than anything else as I held him by the wings. The next
catch was another Gilded. I had to look twice to confirm that it was a
female. Now I was ecstatic. Getting females would be tough I was told.
It wasn't yet 6AM and I had a pair. I saw several more. One time I saw
three Gilded River Cruisers come together to chase each other. But I didn't
manage to catch any more. They flew faster as the sun hit the stream and
by 6:45 they were gone again.
Two and a half hours to St. Louis. Return the rental car, ride the bus
to the terminal. Flight to Cincinnati, flight to La Guardia, bus to train,
train to home. Wife in the car, hug the boys. Scan the cruisers. Go to
bed.
