Description

The false katydids as a group are larger than the meadow katydids, with less membranous, larger and more solid-colored wings. They lack the coneheads’ cones, and are less heavy-bodied than the common true katydid. Round heads are a prominent feature. Bush katydids have a more stretched out overall shape, with proportionately longer narrower wings, than do other members of the false katydid group. The fork-tailed bush katydid is smaller than others in its genus, but physically distinguishing the bush katydids in most cases requires examination of the appendages at the tip of the abdomen. Separating them by song is easier. The song of this one is almost too simple: single tsk sounds, widely separated. It is similar to the secondary song of the greater angle-wing, but is not as loud or sharp, and comes from a lower location than the angle-wing's treetop perch.

DuPage County Notes

The fork-tailed bush katydid can be found on grass, trees, and bushes, especially on edges of meadows, marshes, etc. It also (and perhaps mainly) occurs in trees, both scattered and in forests. Its abundance and distribution are difficult to determine, given the similarity of its simple song to the secondary song of the abundant, widely distributed greater angle-wing. Though called “uncommon” here, that is subject to change.
