Click for larger image	Adults: The potato leafhopper adult is highly mobile, wedged-shaped, green in color, and about 1/8 inch (3 mm) long. The body is widest at the head and tapers toward the wing tips. The front margin of the prothorax is usually marked with six white spots. The life span of females is about 30 days.
	Eggs: Eggs are laid singly within the petioles and veins on the under surfaces of host foliage. The optimum temperature for egg laying is 76°F with no egg laying above 90°F or below 62°F. The eggs, which are about 1 mm in length, hatch in approximately 10 days. Females may deposit 2-3 eggs per day over their life span.
	Nymphs: The potato leafhopper nymph (immature stage) passes through five distinct stages within a period of 12-35 days. The total period from egg to reproductive maturity is about 28 days, under favorable conditions.
