17-Year Locust Sightings

8 posts in this topic

I have seen them every few years.  There are quite a few overlapping broods.  Also, I think that species (magicicada) has a 13 year cycle brood or two as well.  Last year was insane for the annual and 3 year broods here in Frederick.  It was deafening at times.

These cicadas are a 17-year brood due to return en masse in 2021. A fraction are emerging early. I have had several inside my screen porch as they emerge from their shells, which tells me this porch and attached deck was probably in a different state in 2004. 

One appears to have been caught and killed by a spider just as it was about the come out of its shell. I've seen hundred or thousand of cyclical cicadas and their shells in my life, but this is the first I've ever seen in the midst of the final stage of metamorphosis. 

I've seen about 10 or 12 so far, but haven't heard one. I think the birds are picking them off quickly. Which is one reason they normally hatch in the billions. Sheer numbers overwhelm predators.
