The broad-winged tree cricket was the first singing insect species I found (in 2006, the first year of my study) that had shifted its northern range boundary significantly.
In contrast to the jumping bush cricket, this one seems to be moving slowly, but I have not followed it as closely. This year I put some time into locating northernmost singers, and found two locations.
These will be the starting points for next year’s check. The Kane County location is only 1.5 miles south of the southern McHenry-Lake County border line.
