Tettigoniidae

Longhorned grasshoppers and katydids have long, thread-like antennae, four-segmented tarsi, and a flattened, sword-like ovipositor. Most species stridulate; they are known for their loud, high-pitched song in trees during the afternoon and night. In the UK, the dark bush cricket, Pholidopteragriseoaptera, can be heard singing through the night. Most tettigoniid species are plant feeders, but some are predaceous on insects. They are occasionally attracted to lights at night, and accidentally comeindoors. Several species are carried outside their normal range with the movement of commercial fruits and vegetables. The most common of the displaced species entering the UK include Cosmoderus maculatus on bananas from Cameroon, and Jamaicana subguttata and Mastophyllum scabricolle on bananas from West Indies.

This species occurs in the UK, continental Europe, North Africa, and regions of temperate Asia.

Oak bush cricket, drumming katydid, Meconema thalassinum

Adults are about 16 mm long. The body is uniformly pale green; the antennae are inserted between the eyes. Wings are equal to the length of the abdomen; the ovipositor is narrow, and short. This species is commonly found at lights near trees. It is not restricted to feeding on oak trees. It does notstridulate, but the male produces a sound by striking (drumming) its hind tarsi on a leaf. This species is widely distributed in Europe, and has been introduced into northeastern USA.

Pagago thread-legged katydid, Arethaea gracilipes Adults are 30-35 mm long. The body is green and there is a colored strip on the side of the abdomen. They occur on grass and weeds along roadsides in southwestern USA. They are attracted to lights at night.
