Grasshoppers, Crickets, and Katydids of Columbia County, Oregon

Grasshoppers, Crickets, and Katydids are part of the insect order Orthoptera, known for long legs that give them the ability to jump, stiff wings that fold against the body, and noises made by rubbing their wings against each other or against their legs. Some species are considered crop pests. They are most closely related to stick insects (walking sticks) and leaf insects, and somewhat more distantly related to cockroaches, termites, stoneflies, and mantises.
