On Monday (Memorial Day) I was lucky enough to find a lone Magicicada septendecim brood II straggler in Metuchen, NJ. This is a male, and he was about 1.5 inches or 3.8 centimeters long.
Look for orange coloring between the wing and eye to identify Magicicada septendecim:
Cicadas have 3 tiny eyes called ocelli:
Thanks to Elias for noticing the coloration behind the eye that IDs this as a decim.
Nice pics Dan! Good to see that you have been finding stragglers too.
