Update

Circumstances have prevented me from gathering much new blog material for the past week and a half, but I hope to have more to share soon. The bird migration continues, but there’s only one photo in the hopper.

As for singing insects, the first few spring field crickets began singing in Marshall County, Indiana, last week, but I have yet to hear any farther north (DuPage County, Illinois).

The one significant new development came yesterday, as I was running the trails at Herrick Lake Forest Preserve. A grasshopper flew up from the trail in the large meadow of the preserve’s southeast corner. It had hind wings that were bright yellow with broad black edges. This was the first opportunity to take advantage of my recent literature research on possible new singing grasshoppers. It turns out there is only one band-winged grasshopper with that color pattern that matures so early in the season, the sulfur-winged grasshopper (Arphia sulfurea), and so I can already shift one species from the hypothetical list to the verified list for the region.
