Seasonal development and life cycle—Leafhoppers

Leafhoppers go through incomplete metamorphosis in their development. Female leafhoppers insert tiny eggs in tender plant tissue, causing pimplelike injuries.  Overwintered eggs begin to hatch in mid-April. Wingless nymphs emerge and molt four or five times before maturing in about 2 to 7 weeks.  Nymphs resemble adults except that they lack wings; later-stage nymphs have small wing pads. There is no pupal stage. Leafhoppers overwinter as eggs on twigs or as adults in protected places such as bark crevices.  In cold-winter climates, leafhoppers may die during winter and in spring migrate back in from warmer regions.  Most species have two or more generations each year.
