Brood XIII

From Wikipedia, the free encyclopedia

Brood XIII (Brood 13) is one of thirty broods of periodical cicadas that appear regularly throughout the eastern United States. Every 17 years, Brood XIII tunnels en masse to the surface of the ground, lays eggs, and then dies off in several weeks.

Its most recent appearance was in the spring and early summer of 1990 throughout an area roughly enclosed by northern Illinois, eastern Iowa, southern Wisconsin, and a narrow strip of Indiana bordering Lake Michigan and Michigan. The next three appearances will be in 2007, 2024 and 2041. [1] [2]

In the northern Chicago suburb of Highland Park, there is concern about how the cicadas might drown out the music at the Ravinia Festival during May and June, the peak months of cicada activity.
