Pterophylla camellifolia, the common true katydid, is a common North American insect in the family Tettigoniidae (katydids). Within the Tettigoniidae, it belongs to the subfamily Pseudophyllinae (true katydids). Other common names include northern true katydid and rough-winged katydid.[1][2][3]
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
[edit]The 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
[edit]This 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
