The Magicada Brood VI (or maybe X?) is emerging a few years early, possibly due to climate change. They are very numerous in NoVA right now, though their main emergence is in the North and South Carolina Appalachias. Please participate in one of the big citizen-driven science projects and report your circadas to Periodical Cicadas – www.magicicada.org. Reporting is pretty good up in NoVA due to publicity but more reporting is needed in the rest of Virginia.

Umm, yeah, SpellCheck told me so later but not when I wrote the title. Can't edit the title later. My bad.

But, Cicadas (no matter how you spell them), locusts, tree crickets are pretty cool and when they emerge in swarms they are amazing. The fact that global warming seems to have an impact is intriguing. You can personally impact science with your reports, so please help track them, everybody.

Although there are always a "few" every year, we only get the "big hit" every 17 years. Back in '95 we got hit pretty heavy with them, but 2012 was light in comparison. Next hit won't be till 2029.

Global climate change having an impact on the cicada populations is a theory; not a fact.

It's still too early for them. The nights are still too cool. They usually don't emerge around Richmond until late June.

Yes, you are right, I apologize for the sloppy wording. Brood X is emerging 4 years early in the NoVA area. Early emergence has been noted in the past, going back to the 1800's. A detailed discussion of that can be found at Brood X - Cicada Mania

2017 Magicicada Reports shows reported cicada sightings. If you reduce scale to Virginia you will see a heavy cluster in NoVA, but none reported outside of it in the state. Small sightings are scattered around other states with another concentration around the Cincinnati/Columbus area. Not as heavy as DC though.

Shouldn't Richmond be theoretically warmer than NoVa? They emerged here weeks ago.

Are you sure that they are cicadas you're seeing?
With nights in the 50's it isn't too likely that they are out, unless this is a super breed that can tolerate the cold. We don't have those down here
