Return to Newton and Jasper

by Carl Strang

On Monday I returned to Newton and Jasper Counties, Indiana, to survey for singing insects that had emerged since my earlier visits there (Newton County was the site of the bioblitz last year; I went to a new site this time, the Willow Slough State Fish and Wildlife Area). In Jasper County I went back to the Jasper-Pulaski Fish and Wildlife Area, and was especially interested in revisiting the savanna and sand prairie.

The most exciting find was an unfamiliar insect singing loudly from the black oak woodlands of both sites in the early to mid-afternoon. Its song was a series of quick buzzing sounds, as though a sword-bearing conehead (which sings at night) woke up way early and got hold of a megaphone. With that volume at that time of day well up in the trees it had to be a cicada, and when I later referred to sources and listened to reference recordings it was clearly the green-winged cicada, Diceroprocta vitripennis. This is a species I thought I might have heard in DuPage County at the time of the periodical cicada emergence in 2007, but the songs were difficult to separate from the loud Magicicada choruses, and I have not heard it since, until Monday. I did not see one, but hope to get a photo in the future.

Otherwise the singing insects were familiar, though I did pick up a number of county records and heard a few species singing for the first time this year.

Also, a very large, interesting looking grasshopper flew up from the sand prairie and landed on a tree after a graceful flight on its long wings.

It was noticeably larger than the Carolina grasshopper, the most common large grasshopper in the region.

The color pattern, behavior and habitat point to the obscure bird grasshopper (Schistocerca obscura), not a singing insect but an interesting attention-grabber nevertheless.
