Brood X: 'Trillions' of Cicadas to Emerge After 17 Years
Trillions of cicadas are set to emerge from underground in April or May in 15 states and the District of Columbia
WASHINGTON — Trillions of cicadas are set to emerge from underground in April or May in 15 U.S. states and the District of Columbia, from Illinois east to New York and New Jersey and south into Tennessee and Georgia.
The appearance of the group known as Brood X follows a period of 17 years of living underground, feeding on tree roots.
On appearance they live for up to four weeks and spend most of that time mating. The female cicada goes on to lay hundreds of tiny eggs on tree limbs, and the adult cicadas die.
When the eggs hatch, cicada nymphs fall from the tree and burrow into the ground. Here, they'll look for tree roots to feed on and stay underground for up to 17 years.
