The group expected this spring, known as Brood 2, are the offspring of cicadas last seen in 1996. If they follow the same tracks as their parents, they'll emerge in Connecticut, Maryland, North Carolina, New Jersey, New York, Pennsylvania, Virginia, and Washington, D.C.
The genetic mechanism that prompts periodical cicadas to emerge kicks in every 17 years (or every 13 years for other broods) when the ground warms up to 64°F (18°C).
You folks have fun. Down in Texas, we have another couple years before brood IV
