I hate these things. I'm going to have Oklahoma sprayed :-D

But if you just wait until June or July, there will be other genera and species, I promise. Spharagemon should be plentiful out there, for example.

There are others maturing now too. There should be some slant-faced species where the Chortophaga occur, with Eritettix being quite likely. Try some drier more open grassland habitats, gravelly places, sandy places, or bare hilltops, etc. You should start seeing lots of Slant-faced adults, and there will be Xanthippus (if you're not too far east), Pardalophora, and Arphia in the band-wing group. Most of the other band-wing types out now will have brightly colored wings, and some are huge. By June, not only will you see lots more other species, but the Chortophaga will be history (until the eggs start hatching in the fall anyway).
