Habitat Forests, thickets, or fields with lots of shrubs or trees.

Range Eastern US; west to Texas, northeast to Ontario.

Discussion Katydids spend most of their time at the tops of trees where most of the leaves are. Can fly short distances when threatened, but prefers to walk and climb. Flight primarily a downward flutter. If a katydid lands on the ground, it will walk to the nearest tree and climb. Known as the True Katydid because it was the first katydid species to have its call transcribed. It can be heard easily at ground level while chirping from treetops.
