According to the cicada emergence calculator:http://www.cicadamania.com/cicadas/2...gence-formula/
Using a temp of 11.888 *celcius as the mean for April in Coburn, the
cicadas should emerge on 15 May, i.e. tomorrow (about an 80% prob).

Based upon my only experience with this brood in 1991, the cicada
emergence will overlap the spinnerfall of the Green Drake.

And the green drake duns come out with the white peony blooms. Any
one seen any?
