* From the U of I Extension office in February…

For the first time in 221 years, periodical cicada brood XIII and brood XIX will emerge at the same time!

A periodical cicada emergence can be an exciting event to witness! Periodical cicadas emerge from roughly mid-May until late-June, so be ready for a wild start to summer. This is a great time to visit a local state or city park and watch the adult cicadas fly, listen to their calls and look for the nymphs’ shed skins. In neighborhoods with mature trees, some may even find cicadas in their back yards. You can even take part in a citizen science project by reporting cicada sighting locations on the Cicada Safari app.

Brood XIII emerges in the northern half of Illinois and will consist of three species of 17-year periodical cicadas, Magicicada septendecim, Magicicada cassini, and Magicicada septendecula. Brood XIX is called the Great Southern Brood and emerges in the southern half of Illinois. Brood XIX consists of four 13-year periodical cicada species, Magicicada tredecim, Magicicada neotredecim, Magicicada tredecassini, and Magicicada tredecula. Cicadamania.com is a great website to visit to learn more about the individual species emerging. The two broods have an area of overlap in Macon, Sangamon, Livingston and Logan counties in central Illinois. Springfield could be a great location to spot members of both broods.

* “Hyper-sexual ‘zombie cicadas’ that are infected with sexually transmitted fungus expected to emerge this year”…

Matthew Kasson, an associate professor of Mycology and Forest Pathology at West Virginia University, says both of these broods can be infected by a fungal pathogen called Massospora cicadina.

Once the cicadas emerge from the ground, they molt into adults, and within a week to 10 days, the fungus causes the backside of their abdomens open up. A chalky, white plug erupts out, taking over their bodies and making their genitals fall off.

“The cicada continues to participate in normal activities, like it would if it was healthy,” Kasson told CBS News. “Like it tries to mate, it flies around, it walks on plants. Yet, a third of its body has been replaced by fungus. That’s really kind of bizarre.”

Kasson said the reason the cicadas might be able to ignore the fungus is that it produces an amphetamine, which could give them stamina.

“But there’s also something else unusual about it,” he said. “There’s this hyper-sexualized behavior. So, males for example, they’ll continue to try and mate with females — unsuccessfully, because again, their back end is a fungus. But they’ll also pretend to be females to get males to come to them. And that doubles the number of cicadas that an infected individual comes in contact with

Yuck.

* More…

Illinois state entomologist Chris Dietrich said there are two different broods of cicadas emerging this year, one that only comes out every 13 years, and the other coming out every 17 years.

He said these two broods of cicadas have not been out together since 1803.

“These two particular broods of cicadas only come out every 221 years. And it’s really unusual to have two broods that are kind of right next to each other in terms of their geographic distribution that emerge simultaneously,” said Dietrich.
