In the next few days, billions of insects will swarm the East Coast. This is no cause for alarm; it's just a life cycle, and residents along the I-95 corridor can expect to see, but mostly hear, the chorus of cicadas as they come out to mate.
The specific type of cicada, known as Brood II, is not harmful to humans. It emerges every 17 years, and the male cicadas take up posts on trees, singing individually or collectively, to attract females.
The insects grow to about three inches and emerge when ground temperatures reach 64 degrees.
Though there are no options for controlling this cycle, East Coast residents may find earplugs valuable assets for the next two months.
