Cicadas on the march

"Here they come," writes Watershed Post reader Penny Johnson, who snapped this photo of cicadas emerging in a West Hurley garden at 8am this morning. 

This year marks the emergence of Brood II, a group of 17-year cicadas in the Northeast that have spent most of the last two decades underground. And it has begun: As the soil eight inches below the surface hits 64 degrees, larval cicadas are emerging from the ground to molt, mate, lay eggs, and die. 

Downstate on Staten Island, the emergence is underway, the New York Times reports:

In some areas of Staten Island and elsewhere around the Northeast, the early risers have already awakened, to be followed by their fellows when the soil sustains a temperature of around 64 degrees. In patches of parkland near a lake, the empty husks of the nymph-stage bugs are everywhere, left behind wherever a creature squeezed out of a gap in its shell like an extraterrestrial in a Ridley Scott movie.

Cicadas have been spotted emerging in several New Jersey towns as well, CBS News reports.
