Pacific Northwest Katydids

Katydid on Agoseris glauca var. dasycephala at Sunrise, Mt Rainier National Park, Aug. 23, 1996.

Katydids are long-horned grasshoppers, so called due to their long, thin antennae. They get their name from their song, which sounds like "katydid". Most are bright green in coloration, and they can be as large as thumb-sized. Most live in trees, but some live in meadows. The nymphs generally lack wings, while the adults have wings longer than their bodies. Both the nymphs and adults feed on plant materials, although some feed on other insects. The katydids generally do little damage to crops unlike their cousins the grasshoppers.
