The emergence of the cicadas might be most noticeable by their size and sound. Cicadas surface in large numbers, gathered together to protect themselves against their many predators. And their mating calls can't be missed, as the males call out to attract the females in hopes of laying eggs. Then, the adults die out making way for the next generation. Cicada nymphs that hatch will burrow underground until the brood's return in 2038. New York City and much of its surrounding suburbs will probably be sitting this round out. Parts of New Jersey, meanwhile, especially the state's central and southern counties are projected to see a cicada emergence.
