Herpetology Class Trips

This semester, I’m taking a herpetology class. It’s a lot of fun — I get to actually learn about amphibians, and the class has a lab and field component that I’m really enjoying. Part of my final grade will be based on how well I keep a field notebook — and while writing down substrate temperatures quickly gets boring (there’s a reason I’m not an ecologist, dammit), the plus side is that occasionally, there are things like snakes and frogs in my life.

For example, on Labor Day, I wandered down to the southeastern corner of the state with my lab mates, and while the herping wasn’t great, we did manage to find this wonderful Great Plains Ratsnake (Pantherophis emoryi) hiding under a rock near the side of the road.

Yesterday, our whole class piled into a couple of vans, and we hit Schramm State Recreation Area. With thirty eyes fixed on the ground, we managed to find some pretty cool stuff — including a young Eastern Racer (Coluber constrictor) caught in the act of eating a neonate Common Garter Snake (Thamnophis sirtalis).

I admit it’s not my best photo ever (super natural background, eh?) but that’s just cool.

Other finds included large numbers of Blanchard’s Cricket Frog (Acris crepitans blanchardi), a juvenile male Northern Water Snake (Nerodia sipedon), adult Common Garter Snakes (Thamnophis sirtalis), Plains Leopard Frogs (Lithobates blairi), a young Bullfrog (Lithobates catesbeianus) — an invasive species in Nebraska, and, finally, a pair of young Cope’s Grey Tree Frogs (Hyla chrysoscelis), who were hanging out in the park restrooms (cool, damp, and full of insects!) — here’s a portrait of one on a slightly more natural background.

Some Nebraska Natives

I’m moving to Nebraska in August, which means that I should be spending my last months in Texas herping, because the pickings are a lot slimmer up north. But, instead, one of my friends invited me to come up to his Permian paleontological field site in Nebraska this weekend. And since I’ll be doing a Ph.D. in a vertebrate paleontology lab starting in the Fall, I figured that it was probably a good idea to start to familiarize myself with some of the fossil sites in the state. I was spectacularly useless at quarrying things, but I had a good time, and killed a lot of ticks that were trying to suck my blood, so it was overall a productive weekend.

And I took pictures of things! Because that’s who I am, or something.

This is a lined snake, Tripidoclonion lineatum. It was a lifer for me, which is pretty awesome (especially from Nebraska, geeze).

I am also pretty excited by the fact that this is the first gray tree frog that I’ve been able to narrow down to species. Hyla chrysoscelis and H. versicolor are basically distinguishable only from their calls, which can make IDing them pretty tough. However, since we found this little guy while he was calling, I can tell you that he is, in fact chrysoscelis, and not versicolor. And then the internet informed me that versicolor doesn’t even make it in to Nebraska, but I nonetheless felt all herpetologically talented for IDing a frog based on a call.

And here’s something with an exoskeleton, to keep you entomophiles quiet. This was probably one of the most annoying things that I have ever photographed — I was dealing with the fact that this beetle was both extraordinarily iridescent, and extraordinarily filthy, which meant that my flash was basically useless. I ended up relying primarily on natural light for this shot, although I did use a little bit of off-camera flash to brighten things up. Not a fun picture. But I did bring the beetle back with me, so I may try to clean him up and white box him later.
