These insects differ radically from the scales, mealybugs, aphids, etc. that we examined last class period. This group is large and diverse, with various forms, colors, and sizes. Leafhoppers also may produce honeydew. I have selected this insect as a typical example of a leafhopper.
Adults are usually yellow to pale green, and the wings are held rooflike over the body.
Once here, it may undergo several generations each year. This pest can be found on almost 200 kinds of plants, including flowers and ornamental trees. As this insect feeds, it injects saliva into the phloem which can cause the plant to exhibit disease-like symptoms. These insects commonly move quickly sideways or backwards. Adequate screening and sealing of door edges can reduce infestations in a greenhouse.
