Memorial Day weekend brought a reunion with my brother, Gary, in our hometown of Culver, Indiana. Among the many reminiscences and activities were a few visits to places where I hoped to find early season singing grasshopper species. By the time I got home I had accumulated 5 county records for sulfur-winged grasshoppers.
Along the way I found color variations, between the genders and between locations.
On the whole, though, females were much less variable than males.
Males generally were darker than females and, as is typical in grasshoppers, were smaller.
Tibia color also was not consistent. This seems surprising, as the behavior of grasshoppers when they meet often includes a display of tibias.
There still is time to find sulfur-winged grasshoppers in more of the 22 counties of the region I am surveying, and I will be interested in seeing how these variations play out.
