(John Obermeyer, Purdue University)
Common Name: Treehopper

Order: Homoptera

Family: Membracidae

Pest Status: Treehoppers feed on the leaves of many kinds of trees and shrubs, sometimes causing injury to the plant.

Appearance: Treehoppers are usually less than 1/2-inch long. They have enlarged pronotums that are variously developed into horns, knobs, and other strange shapes depending on the species. Color also varies depending on species, but it usually ranges from green to brown.

Life Cycle: An adult female deposits eggs singly or in masses, either inserted directly into living tissue or on the surfaces of plants. The eggs remain in the plant through the winter and hatch in spring. Nymphs molt five times prior to reaching the adult stage. Treehoppers usually have multiple generations per year.

Where to Collect: Treehoppers can be collected by sweeping young trees and shrubs with a net in late summer and early fall.
