Listroscelidinae

Belongs within: Tettigonioidea. The Listroscelidinae are a group of carnivorous katydids that are most diverse in the South American tropics and the Indo-Malayan region. They are distinguished by a series of long, curved spines on the fore tibiae that may be used in capturing prey (Rentz 1996). Characters (from Rentz 1996): Fastigium of vertex narrow,… Continue reading Listroscelidinae

Grylloidea

Belongs within: Apohaglida.Contains: Gryllinae, Nemobiinae, Eneopterinae, Oecanthinae, Gryllotalpinae, Mogoplistinae, Anaxipha, Trigonidium, Laupala. The Grylloidea include the crickets, a mostly dorsoventrally flattened, terrestrial group of orthopterans that are usually omnivorous. Their fore wings have a fan-like pleating intercalary triangle, and veins RA, RS and 1MA1 are fused completely or at least in part (Gorochov & Rasnitsyn… Continue reading Grylloidea

Gryllinae

Belongs within: Grylloidea.Contains: Gryllus. The Gryllinae, field crickets and house crickets, include the most familiar members of the cricket family. Some species, such as the tropical house cricket Gryllodes sigillatus, have become abundant worldwide in association with human activity. The black field crickets of the genus Teleogryllus may be serious pasture pests in parts of… Continue reading Gryllinae

Acridinae

Belongs within: Acridoidea. The Acridinae are a group of grasshoppers in which the prosternum lacks a central tubercle or spine (Rentz 1996). They include the cone-headed grasshoppers of the genus Acrida, relatively large grasshoppers with an elongate head and flat sword-shaped antennae. Members of the genus Orphulella are abundant in the Americas and have constricted… Continue reading Acridinae

Acrydiinae

Belongs within: Caelifera. The Acrydiinae are a group of grasshoppers in which the wings and abdomen are concealed by a large rearwards projection of the pronotum. The Bombay locust Acridium succinctum is a southern Asian species that has historically been recorded forming swarms though such behaviour has not been observed since the very early 1900s.… Continue reading Acrydiinae

Pseudophyllinae

Belongs within: Tettigonioidea. The Pseudophyllinae, true katydids, are a group of often large katydids found in tropical regions, often on the margins of rainforests (Rentz 1996). Characters (from Rentz 1996): Antennae with bases touching or nearly touching; sockets strongly rimmed, especially on dorsal margins. Thoracic auditory spiracle small, inconspicuous, not hidden by pronotum. Tibial auditory… Continue reading Pseudophyllinae

Tridactyloidea

Belongs within: Caelifera. The Tridactyloidea are a group of burrowing, cricket-like orthopterans characterised by tarsi with two segments in the fore and mid legs, and only a single segment (if tarsi are present at all) in the hind legs. The pygmy mole crickets of the Tridactylidae retain hind legs suited for jumping but the sandgropers… Continue reading Tridactyloidea

Caelifera

Belongs within: Panelcanida.Contains: Tridactyloidea, Eumastacoidea, Pyrgomorphidae, Acridoidea, Acrydiinae. The Caelifera, including the short-horned grasshoppers, are a clade of orthopterans characterised by the reduction of the antennae. As well as the true grasshoppers of the Acridomorpha, this clade includes the pygmy grasshoppers of the Tetrigidae, small and camouflaged grasshoppers characterised by the posterior extension of the… Continue reading Caelifera

Acridoidea

Belongs within: Caelifera.Contains: Ommexechidae, Romaleidae, Pamphagidae, Stenobothrus, Oedipodinae, Ommatolampinae, Catantopinae, Oxyinae, Cyrtacanthacridinae, Melanoplus, Acridinae, Chorthippus. The Acridoidea include the typical grasshoppers and locusts. The latter are those species whose life cycle may include a gregarious phase in which they form dense migratory swarms, potentially causing significant damage to vegetation, including crops, where they occur (Rentz… Continue reading Acridoidea
