Periodical cicadas are only found in the eastern half of the United States
The 17-year Brood XIII is the only one known to emerge in Wisconsin, though only in the southernmost counties. The last hatch was in 2007.
These cicadas have just emerged and shed their exoskeleton. Their new adult body and wings are exposed. “The wings will inflate with fluid and expand, and their new skin will harden—which typically takes several day. .
This bunch of cicadas will mate and lay eggs up in the tree branches. When the eggs hatch the nymphs will fall to the ground and burrow into the dirt and live underground for 17 years, feeding on tree roots, before they emerge and the whole cycle starts over again.
These holes are everywhere!
Cicadas do not bite, but with so many around it is startling if one flys too close! Or lands on you.
They will live above ground for about 4-6 weeks before dying.
And for the next month
It will be noisy here in my woods!
