Leafhopper

Leafhopper, about 70 genera and over 700 species of slender, sucking insects of the family Cicadellidae. Leafhoppers may be brilliantly colored, green, or brown, and are 1/20–1/2 in (1.3–12.7 mm) long. They occur worldwide and on almost any type of plant, particularly fruits, grains, sugar beets, and roses. Leafhoppers carry fungus and bacterial diseases and in large numbers may cause severe crop damage.
