The DNR has confirmed the emergence of a species of insect that only comes out occasionally.
Periodical Cicadas are exclusive to the eastern half of the United States, with seven species identified, four featuring a 13-year life cycle and three with 17-year cycles.
These species are categorized into 15 different “broods” or year classes. Among them, the 17-year Brood XIII is notable for its emergence in Wisconsin, specifically in the state’s southernmost counties.
Other regions in the Midwest, such as Illinois and areas further south, will witness the simultaneous emergence of both Brood XIII and the 13-year Brood XIX.
This unique event marks the first time these two broods have emerged in the same year since 1803, approximately 221 years ago.
The loud mating calls of cicadas can be bothersome, and their remains post-mating can create a nuisance as they cover the ground.
Despite their noisy presence, cicadas are harmless as they do not bite or sting.
In fact, some individuals consume cicadas, referring to them as “tree shrimp”.
These insects emerge in large numbers, with densities ranging from tens to hundreds to thousands per acre.
They feed on plant fluids from deciduous plants and shrubs for four to six weeks without causing significant harm to healthy mature plants.
The current emergence of cicadas in southern Wisconsin is expected to continue into June, with the next appearance in the state forecasted for 2041.
Residents spotting cicadas on their property or public areas are encouraged to report sightings on the Cicada Safari app to assist in tracking the co-emergence of Broods XIII and XIX.
