The big cohort of cicadas doesn’t return to the mid-Atlantic region until 2021.
I remember them in Washington DC in 1986. I was stationed at Bolling AFB, just got married (in May) and moved to an apartment near Camp Springs, Maryland, just south of DC.
Me and my bride would walk our dogs in the nearby woods and fields. The cicadas sounded like a pulsating alien spaceship landing. It was eerie!
Yep. This year’s crop of 17 Year cicadas is Brood V.

The really big one is Brood X – “The Great Eastern Brood”. That Brood last emerged in 2004 (and living in Maryland, I remember it very well and also as a child living in Central PA in 1970) and isn’t due to emerge again until 2021.

Brood V isn’t nearly as large and living in South Central PA, it doesn’t appear to be likely to make much of a “buzz” around here. Of course there are some cicada broods or stragglers that emerge every year, but here in the Mid-Atlantic it is Brood X that is the big one.
