While my main focus at the Kankakee Sands bioblitz was on observing singing insects, I also was noting other species along the way, and was interested in others’ observations of singing insects. Someone in the Purdue entomology group collected a female bush katydid, for example.
Female bush katydids are tricky, but I’m pretty confident that this is a Texas bush katydid. The sharp bend in the ovipositor, especially the inward or upper edge, narrows it down to a very few species. A broad-winged bush katydid would have broader wings, and a fork-tailed bush katydid would have a reddish-brown rather than green ovipositor. The colors and shapes of other structures around the ovipositor, and the shape of the ovipositor itself, match those of the Texas bush katydid, which is a common species of prairies like the one where this insect was collected. I didn’t hear any singing, but in DuPage County these tend to start up later in the season.
I saw a number of little yellow butterflies that had the markings of sulphurs but were unfamiliar to me.
A milkweed leaf beetle turned up in a sweep sample in one of the prairie areas.
Alyssa noted that I had picked up a hitchhiker at one point.
One of our nets caught an impressive jumping spider.
Finally, I photographed a grasshopper nymph that I thought might belong to a stridulating species, but I think it is in the wrong group.
Grasshoppers are a group I usually will need to collect for identification.
