Brood XIII is a 17-year periodical cicada brood composed of Magicicada species that emerges in large numbers across parts of the U.S.
Midwest.
When soil temperatures reach about 64 degrees F at 8 inches depth, nymphs emerge from the ground, molt to adults, and males produce loud choruses during daytime hours.
Emergences are locally intense but short lived over several weeks.
