I have made a correction to yesterday’s post on green-winged cicadas. I always check my posts when I get to work, to make sure nothing is lost in the translation to another computer. In the process of checking links, I went to the Cassin’s 17-year cicada portion of the Michigan cicada website. There I saw something I hadn’t noticed before, mention of “Court II” and “Court III” signals. The Court III signal is produced by a male cicada as he connects with a female for mating.
When I played the Court III signal recording, it proved to be what I had attributed to green-winged cicadas in 2007. That both corrected my impression of Diceroprocta in DuPage County, and removed any confusion about my observations in 2013.
