Common True Katydid

Fascinating facts about the Common True Katydid

• Spanning from the forests of southeastern Canada down to the swamps of Florida, the common true katydid blankets a huge stretch of eastern North America. It can reach up to 50 mm (2 in) in length, making it one of the larger insects you'll find perched in tree canopies. Its broad distribution means it experiences a wide range of temperatures, which in turn drives the temperature-dependent rhythm of its signature three-pulsed "ka-ty-did" song. This size and range let the katydid dominate the foliage niche, shaping the soundscape of countless woodlands.
• Four distinct song types. Northern groups sing two, three, or four pulses per phrase. Southeastern crowds produce a faster, multi-pulse chorus. Southwestern insects simplify to one or two pulses. Central Iowa form rattles out eight to fifteen pulses.
• First catalogued as Locusta camellifolia, the insect was reassigned when Kirby erected the genus Pterophylla in 1825. Today three subspecies are recognized, each tied to a specific type locality: the nominal camellifolia in the United States, dentifera from Hempstead County, Arkansas, and intermedia from Biloxi, Mississippi. This taxonomic history shows how subtle regional differences earned formal scientific distinction over two centuries.
• Unlike many of its relatives that launch into the air, this katydid is practically flightless, preferring to walk, run, or hop along branches. It feeds on canopy foliage. It has a loud, rasping three-pulsed song.
• Classified in the family Tettigoniidae and subfamily Pseudophyllinae, the common true katydid. Its widespread presence from Maine to Florida.
