"Cicada Emergence: 2024 Map, Diet, and Facts to Know"

The 17-year "Northern Illinois Brood" (Brood XIII) and the 13-year "Great Southern Brood" (Brood XIX) of cicadas are set to emerge in 2024, spanning across 17 states with some overlap in Illinois and Indiana. Michigan may not see as many cicadas as other states, and the emergence is expected to begin in late April or May when soil temperatures reach 64 degrees Fahrenheit. Cicadas are harmless insects that emerge in groups known as "broods" once every 13 or 17 years to reproduce, and they do not pose a danger to humans or animals. If you want to witness the emergence, heading to Indiana and Illinois is recommended.
