Well my picture window was all around the East coast. We arrived just in time for the 17year cicada hatch. Only saw a few at my mother’s place but my brother said his yard was over run with newly hatched cicadas (they borrow up from deep underground) and the discarded shells. He sent this picture. They are harmless, lay new eggs and die. The new pupae fall to the ground and burrow down for 17 more years.
