King crickets

Definition

Common name for members of the family Anostostomatidae (order Orthoptera), a group of large, flightless or short-winged insects distributed primarily in the Southern Hemisphere. The name is used in Australia and South Africa, where these insects occupy ecological niches similar to those filled by wētā in New Zealand (also members of Anostostomatidae). King crickets are characterized by robust bodies, powerful mandibles, and often nocturnal habits; many species are detritivores or omnivores. The family has undergone taxonomic revision, appearing in literature as Mimnermidae or Henicidae.

Etymology

From "king" (suggesting large size or imposing appearance) + "crickets", though they are not true crickets (Gryllidae) but rather members of a distinct orthopteran family

Example

The Parktown prawn (Libanasidus vittatus), a notorious suburban pest in Johannesburg, is a king cricket known for its large size, defensive stridulation, and tendency to enter houses during summer rains.

Synonyms

• wētā (New Zealand usage, same family)
• Anostostomatidae (technical)

Usage Notes

Regional common name: "king crickets" in Australia and South Africa versus "wētā" in New Zealand for the same family. Not true crickets (family Gryllidae); the common name reflects superficial resemblance and large body size. Taxonomic synonyms Mimnermidae and Henicidae appear in older literature. Some authors restrict "king cricket" to Australian species, but broader usage encompasses Southern Hemisphere Anostostomatidae generally.
