South-central Indiana was spared from the periodical cicada brood emergence this year, but annual cicadas are still arriving. Annual cicadas emerge around July when the soil warms up and stick around through the fall.
“The cicadas out now are the annual cicadas that we have every year,” said Luke Jacobus, professor of Biology at Indiana University in Columbus. “Some people call them dog day cicadas because they come out during the dog days of summer.”
Annual cicadas are large and green and black, unlike smaller periodical cicadas that are red-orange and black.
Annual cicadas emerge every year. Periodical cicadas emerge every 13 or 17 years.
“Central Indiana was not part of the double emergence of 13- and 17-year periodical cicada brood that occurred to our west,” Jacobus said.
Cicadas emerge from underground and lay their eggs inside the branches of trees. They live for around 2 to 5 years.
