Dedicated to cicadas, the most amazing insects in the world.
What is the time period from when periodical cicadas emerge and shed, to when they begin to actually chorus? While I’m an entomologist, cicadas are not my specialty,
but they fascinate me. I’m heading on my first search, mostly in an area south of my county of Schuylkill county, PA, where some reports have begun to come in. Our county, historically is primarily Brood II, and I will in the coming weeks be attempting to locate pockets of Brood X here. Most my search will be targeting the southern tier of our county, especially more remote areas.
First, their bodies need to fully sclerotize (harden) which can take 2-3 days. If you see white/gray markings on their mesonotum, that’s an indication that they’re not get fully sclerotized. After a few days, you might hear them try to sing or put out a distress sound when handled, that’s a good sign they’re ready to sing.
Then they need a critical mass of other male cicada to form a chorus. Depending on the species, some prefer to be at a certain height in trees before they’ll chorus. M. cassini prefers to be higher up.
They’ll also need the right weather and light conditions — sunny, not too cool – not too hot. And
For the best cicada experiences, would the Smoky Mountain area near Knoxville and Owensboro, KY be good places in mid-May 2021? I will be making a cross-country trip to see them and wouldn’t want to miss this massive brood. Thank you.
Knoxville itself, but not the mountains.

I have seen 4 of the red eyed periodical cicadas this week. Moving about and one emerging from its exoskeleton on a crepe myrtle trunk. We are on Arthur Minnis Road in Hillsborough NC and last saw these in full force May of 2011. Are these stragglers of Brood XIX?
Would appreciate any information! Thanks,
@Ippy, that sounds like Brood XIX emerging 4 years early — very unusual for a 13 year brood — but others are reporting this as well! Thanks!
they are all over my yard this week in south Charlotte NC!
