There haven’t been many new posts in this blog recently because mainly I am going after the low hanging fruit. In other words, most of my research time has been going into checking new counties and new sites, as well as return visits to sites visited earlier in the season, to build my database of singing insect species locations. Though this is productive work, most of that product consists of added locations for common species. That’s not exactly fodder for blogging. A few interesting points have come out, however.
Last week I was working in Indiana. The weather was unseasonably cool, but there was plenty of singing action. In Fulton County I heard a broad-winged bush katydid singing, which establishes that northern species down to the southern edge of the survey region. Clearly they are fewer there than farther north, however. As I drove the rural roads in temperatures that were dropping rapidly to the mid-50’s F, I started hearing a strange, unfamiliar song coming from wetter locations. It was a kind of slow, fluttering buzz, reminiscent of the protean shieldback but much louder, and the buzzes were in repeated short bursts. I pulled off at one such location, and soon realized that these were slightly musical coneheads, their songs altered by the cold, but still singing in lockstep unison. I also found that species in Pulaski County, so they are widely dispersed at least in the northwest Indiana counties.
On the way back home I explored some sites in Lake County, Indiana. The best of these was the Hoosier Prairie Nature Preserve. This is a relatively large, high quality prairie and savanna property. Broad-winged bush katydids were abundant there.
On the way to Hoosier Prairie I passed a sign with a familiar name.
Tom Sporre was in the Purdue wildlife undergraduate program a year ahead of me. Personable and proficient, he went on to become a prominent Indiana waterfowl biologist who died much too young. I was pleased to see a marsh and prairie set aside under his name.
