Director of the University of Wisconsin-Madison’s Insect Diagnostics Lab PJ Liesch received the first reports of Brood XIII cicadas in Wisconsin this year out of the Lake Geneva area just over a week ago. With some of the best-documented historical cicada activity in the state, Lake Geneva could very well be Wisconsin’s “bug central” this summer. Residents have already shared photos of cicadas covering tree trunks, sidewalks and other surfaces.
