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.
