(John Obermeyer, Purdue University)
Common Name: Katydid

Order: Orthoptera

Family: Tettigonidae

Pest Status: Katydids are very minor pests that feed on leaves and make a loud, irritating noise during the evening hours.

Appearance: Adults range in size from 1 1/4 to 5 inches long. Most katydids are green with leaf-shaped wings that are held roof-like over their bodies. They have the general shape of grasshoppers with antennae usually longer than their bodies and large hind legs.

Life Cycle: Females lay gray, oval, flat eggs in leaves where they feed. Nymphs appear in late spring and require two to three months to mature. There is one generation per year.

Where to Collect: Katydids are found in trees and on other plants in grassland areas and forests. They are particularly attracted to light sources.
