Brood XIV
Brood XIV or Brood 14 is a population of the "Periodic Cicadas" ( Magicicada ) in the northeastern United States . Every 17th year Brood XIV cicadas burrow en masse to the surface of the earth, lay eggs and die within a few weeks.
At the beginning of the 20th century, the entomologist Charles Lester Marlatt identified 30 different populations, of which around 15 could also be confirmed over the years. Brood XIV is one of the 12 populations with a life cycle of 17 years. The last occurrence occurred in spring and summer 2008. The next occurrences are expected in 2025 and 2042. Brood XIV appears in the same year as Brood V, but due to the spatial separation, a relationship is unlikely. So far only cicadas of the species Magicicada septendecim have been detected in this population . Premature occurrences occurred in 2003 and 2006. The population spans southern Ohio , Kentucky , Tennessee , Massachusetts , Maryland , North Carolina , Pennsylvania , northern Georgia , western Virginia and West Virginia , and parts of New York and New Jersey . The 4 cm long (1.5 in) black insects cannot sting or bite. As soon as they reach the surface of the earth, they molt, leaving the empty larval skins on the ground. They climb trees and bushes, mate and die after about two weeks. Up to one million specimens per hectare (2.5 acres) can occur.
2008
In 2008, local boundaries were reported in Massachusetts ( Mashpee , Falmouth ) and damage to trees in North Carolina.
