Pterophylla camellifolia

Description

Pterophylla camellifolia, the common true katydid, is a common North American insect in the family Tettigoniidae ("katydids"), in the order Orthoptera ("grasshoppers, crickets, katydids"). Within the Tettigoniidae, it belongs to the subfamily Pseudophyllinae ("true katydids"). Other common names include "northern true katydid" and "rough-winged katydid". The loud, rasping, three-pulsed song of the male of the nominate northern subspecies (“ka-ty-did”) is the source of the vernacular name “katydid” as applied to any tettigoniid.
