Cicadas in Illinois

Around 22 species of cicadas call Illinois their home. Two types of cicadas are common in the state – the annual and periodical. Annual or dog day cicadas emerge yearly, while the periodical ones come out every 13 or 17 years. The state’s northern half has the 17-year cicadas, and the 13-year cicadas can be seen in the southern half.

The periodical cicadas emerge in mid to late May when the soil temperature reaches 64oC after soaking in the rain. The brood X is the largest among them. The other broods of the state are I, III, XIX, and XIII. The annual cicada season is from July to September.
