Oblong-winged katydids frequent the understory of deciduous forests, shrubs, and tall weeds, mostly in damp places. This species of katydid is commonly found on goldenrod and other related plants along fences and the edges of thickets. In open weedy habitats with tall vegetation, they perch near the top of plants to sing.
This species of katydid is typically green, but can be pink, orange, tan, brown, or yellow, though it is rare to find these in the wild. An interesting article that discusses genetics of katydid coloring can be found in a blog from Scientific American.
Adult abundance peaks once a year between late June and mid-August depending on the latitude, and the average adult lifespan is four to six months.
