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.
The horsehair worm Paragordius varius is an internal parasite and can control the behaviour of its cricket host and cause it to enter water, where the parasite continues its lifecycle and the cricket likely drowns. [29] The larvae of the sarcophagid fly Sarcophaga kellyi develop inside the body cavity of field crickets. [30]
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.
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.
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.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets.Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (e.g. Imms [3]): taxa such as the tree crickets, spider-crickets and their allies, sword-tail crickets, wood or ground crickets and scaly crickets have been ...
Anostostomatidae is a family of insects in the order Orthoptera, widely distributed in the southern hemisphere. [1] It is named Mimnermidae or Henicidae in some taxonomies, and common names include king crickets in Australia and South Africa, and wētā in New Zealand (although not all wētā are in Anostostomatidae).
