We had a ton of fun doing this "class" at RBNC, called "Insects on the Prairie". We caught bugs ourselves and learned about them. Some of them that we saw (plus many more I am forgetting) are: stink bugs, katydids, grasshoppers, hopping spiders, tree insects, plant insects, crab spiders, inchworms, some kind of wasp, a couple kinds of butterflies, dragon flies and we even caught a tree frog, which they said is really hard to do.
Let me tell you though, it was FREAKIN' HOT there. Well, anywhere outside it was. It was over 90 degrees with humidity in the upper 70's, so the heat index was in triple digits.
