The loud, rasping, three-pulsed song, rendered "ka-ty-did", of the male of the nominate northern subspecies is the source of the vernacular name "katydid” as applied to any tettigoniid.[4] It is a nearly flightless species that, in contrast with other katydids, often walks, runs, or hops rather than leaping or flying.[5] It lives in the canopy of deciduous trees, where it feeds on the foliage.[4][5] It can reach up to 50 mm (2 in) in length.[4]
Song
editThe singing rate is temperature dependent.[6][7] Four populations of this species can be distinguished by song characteristics:[4]
- The two-, three-, or four-pulsed song of northern populations, as described above;
- The faster song with more pulses per phrase, often heard in large, synchronized choruses common to the Southeastern populations;
- The one- or two-pulsed song of Southwestern populations; and
- A song of 8 to 15 pulses heard only in central Iowa.

Taxonomy
editThis species' original scientific name was Locusta camellifolia. The genus Pterophylla was created for it by Kirby in 1825. Three subspecies are recognized for P. camellifolia:[3]
- Pterophylla camellifolia camellifolia (Fabricius, 1775) – type locality is in the United States
- Pterophylla camellifolia dentifera (Hebard, 1941) – type locality is Hempstead County, Arkansas, United States
- Pterophylla camellifolia intermedia (Caudell, 1906) – type locality is Biloxi, Mississippi, United States
