Ripipterygids are small, often dark-colored, cricket-like orthopterans, between 3 and 14 mm in length. They closely resemble the related tridactylids . Like tridactylids, they have greatly expanded hind femora , and have the ability to swim and jump from the surface of water.
Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, thin tibiae, and long, slender antennae. The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs.
Wētā is a loanword, from the Māori-language word wētā, which refers to this whole group of large insects; some types of wētā have a specific Māori name. [2] In New Zealand English, it is spelled either "weta" or "wētā", although the form with macrons is increasingly common in formal writing, as the Māori word weta (without macrons) instead means "filth or excrement".

Velia caprai, known as the water cricket, is a species of aquatic bug found in Europe. It grows to a length of 8.5 mm (0.33 in) and is stouter than pond skaters of the family Gerridae . It is distasteful to predatory fish, engages in kleptoparasitism , and can travel at twice its normal speed by spitting on the water surface.
Apart from scrabbling over the water or swimming, some species actually can jump off the water surface. It is probable that the natatory lamellae are what makes such implausible leaps possible. The plates also may aid jumping on land, which Tridactylidae certainly can do impressively.
Orthoptera (from Ancient Greek ὀρθός (orthós) 'straight' and πτερά (pterá) 'wings') is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā.
The Ommexechidae and Tristiridae are South American, and the Lentulidae, Lithidiidae and Pamphagidae are mainly African. The Pauliniids are nocturnal and can swim or skate on water, and the Lentulids are wingless. [16] Pneumoridae are native to Africa, particularly southern Africa, and are distinguished by the inflated abdomens of the males. [18]
Spinochordodes tellinii is a parasitic nematomorph hairworm whose larvae develop in grasshoppers and crickets.This parasite is able to influence its host's behavior: once the parasite is grown, it causes its grasshopper host to jump into water, where the grasshopper will likely drown.
