The males aggregate in chorus centers and call there to attract mates. Mated females lay eggs in the stems of woody plants. Within two months of the original emergence, the life cycle is complete and the adult cicadas die. Later in that same summer, the eggs hatch and the new nymphs burrow underground to develop for the next 13 or 17 years.
It lives in semi-permanent burrows and can reside in or escape to deeper soil layers. [4] Its activity is limited by temperature and humidity. High soil and night air temperatures inhibit activity, as do low night moisture and dry soil. During such times, particularly in the summer, the worms will retreat to the deepest parts of their burrows.
Although in general, the feeding activities of the nymphs do little damage, during the year before an outbreak of periodic cicadas, the large nymphs feed heavily and plant growth may suffer. [111] Some species have turned from wild grasses to sugarcane , which affects the crop adversely, and in a few isolated cases, females have oviposited on ...

New England has two primary tick species — the black-legged or deer tick, and the dog tick. Both are most active in the spring and summer. The deer tick is smaller but carries Lyme disease.

Larvae undergo 7–44 days of hardening and then climb vegetation (e.g. to the tips of leaves), from where they attach to a passing host.
