One consequence of this year’s 22-county survey of singing insects is an improved understanding of how some species tail off in density toward the edge of their range. Earlier I highlighted this theme for the lyric cicada and jumping bush cricket. Today begins a series of 3 posts focusing on additional species, beginning with the confused ground cricket.
This is a woodland species, well distributed in the region but with a northern range limit within the 22-county area.
They are spottily distributed throughout the region, but usually in good numbers where they occur, especially toward the south. There are plenty in DuPage County, one of the two northernmost Illinois counties marked on the map. Kenosha County, Wisconsin, is marked because I heard a tiny group of confused ground crickets singing at the New Munster State Wildlife Area. I searched a number of other likely looking spots in that county and the other two Wisconsin counties, without finding this species. It was late enough in the season, though, that I need to make an earlier effort next year, and also to seek them in the other unmarked counties.
