Further north the weather has been too cool but the emergence of Brood II emergence isn't expected to be too far away
The cicadas invasion of the East Coast has begun, with the insects spotted everywhere from Virginia to Massachusetts.
The infestation, named Brood II by scientists, has not been seen since 1996. Before that it last appeared in 1979.
So far the majority of sightings have been in Virginia and other southern states, where some people have found hundreds in their backyards accompanied by the insects' loud chorus call.

The invasion has arrived: Cicadas swarm outside a house in Fredericksburg, Virginia, while two cats look on through a screen door
Further north the weather has been too cool in the likes of New England and New York for a full-blown Brood II emergence, but it isn't expected to be too far away.
Cicadas are expected to emerge from the ground in the billions in the next couple of weeks as soil temperature reaches 64 degrees Fahrenheit.
