Egg -- The white, elongate eggs are 1 mm or less in length.
Nymph -- The pale, wingless nymphs are smaller than adults but similar in shape.
Host Plants -- Leafhoppers infest several hundred kinds of cultivated and wild plants.
Damage -- Leafhoppers retard the growth of grass by piercing stems and leaves with their needle-like mouthparts and extracting sap. This type of feeding causes infested areas to have a whitened or bleached appearance. This symptom can be mistaken for drought or disease damage. Newly seeded lawns are sometimes killed by leafhoppers.
Life History -- Leafhoppers may overwinter as eggs or adults. Resuming activity in the spring, the adults begin to feed and mate. Females insert 75 to several hundred eggs, singly, into the leaf veins of tender new foliage. About 10 days later, nymphs emerge. Over a period of 12 to 30 days, these immature leafhoppers feed on new leaves and develop through five instars. The fully grown nymphs then molt to become adults and the life cycle is repeated. Leafhoppers produce one to four generations each year depending on the latitude and the particular leafhopper species.
