The Indiana Forest Alliance, a non-profit conservation organization, has been sponsoring a species survey in portions of two state forests in southern Indiana. As it consists of repeated weekend sessions over a period of years, they are calling it an “ecoblitz” rather than a bioblitz, which is a one-time event limited to a 24- or 48-hour time span. I went down for a weekend last fall, and returned in early August to complete the singing insects portion of the survey.
The area is forested, except for some small areas of tall, dense herbaceous growth in stream bottoms. The singing insect fauna consequently is mainly of forest species.
Confused ground crickets were common on the forest floor.
Say’s trigs by the hundreds sang in the open herbaceous areas.
Widely scattered small groups of rattler round-winged katydids could be heard at night.
This nymph is recognizable as a male fork-tailed bush katydid by the distinctive appendages at the tip of his abdomen.
Some of the other species that sang for us were swamp cicadas, Nebraska coneheads, lesser angle-wing katydids, jumping bush crickets and common true katydids.
I also helped with photography at a night-time moth survey at illuminated sheets.
This small-eyed sphinx was one of the two hummingbird moths we attracted.
A blinded sphinx also dropped in.
A grape leaffolder
This lesser grapevine looper appears to be sending out pheromone.
A Cope’s gray treefrog hopped in, possibly sensing the smorgasbord we had created.
