Seasonal development
and life cycle—Leafhoppers
Females insert tiny eggs in tender plant tissue, causing pimplelike injuries. Wingless nymphs emerge and molt four or five times before maturing in about 2 to 7 weeks. 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. |
