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 2002). Authors have differed as to whether all living grylloids should be included in a single family Gryllidae or whether distinctive groups such as the Gryllotalpinae and Myrmecophilinae should be placed in their own families. The Baissogryllidae and Protogryllidae are two fossil families related to modern crickets known from the Late Jurassic (Gorochov & Rasnitsyn 2002).

Among modern taxa, the Myrmecophilinae, ant crickets, are a group of very small, humpbacked crickets specialised for living in ant nests. The Phalangopsinae, spider crickets, are long-legged, soft-bodied crickets that are often gregarious and are typically found in secluded habitats (Rentz 1996).The Pteroplistinae are found in the Asia-west Pacific region where they are a significant part of the forest cricket fauna (Otte 1994). The Pentacentrinae are small crickets lacking a stridulatory file on the wings and bearing only an anterior auditory tympanum on the fore tibia (Rentz 1996).

The Trigonidiinae, sword-tailed crickets, are relatively small, slender crickets found primarily in damp habitats whose vernacular name comes from the sword-shaped ovipositor of females, used for inserting eggs into plant tissue. A significant radiation of trigonidiines has been described from the islands of Hawaii, including species assigned to the genera Trigonidium, Laupala and Prolaupala (Otte 1994).
