Stilpnochlora couloniana

Stilpnochlora couloniana is a species of phaneropterine katydid in the family Tettigoniidae, native to southeastern United States (Florida and Georgia; the only Steirodontini in the US), the Bahamas and Cuba. It is known as the giant katydid (a name also used for some other species) and it is the largest katydid in the United States, with an average length of 6.6 cm (2.6 in) in adult males and 7.8 cm (3.1 in) in adult females. Individuals from Cuba tend to grow 5–10% larger than those from the United States. They are sometimes kept as pets.
