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 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.
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.
