WAYNE - Cicada sightings have begun in areas of the Garden State. 

The large insects have been spotted near Packanack Lake in Wayne.

The Northeast is expected to see billions of cicadas as they emerge from underground nests this summer.

One landscaper told News 12 New Jersey that the insects are fairly harmless.

"They really don't do anything," landscaper Bob Butler says. "They make noise when the male's looking for a mate. That's all they do."

If you're looking for a snack, National Geographic says cicadas are an excellent high-protein, low-carband gluten-free food source.
