Carabidae

Definition

A large, cosmopolitan family of beetles (order Coleoptera, suborder Adephaga) containing more than 40,000 described species. Members are primarily cursorial ground beetles with thread-like antennae, filiform mandibles, and typically dark, often metallic coloration. Most are predatory as adults and larvae, though some lineages are herbivorous or omnivorous. The family includes familiar subgroups such as tiger beetles (Cicindelinae), bombardier beetles (Brachinini), and snail-eating beetles (Cychrini).

Etymology

From the type genus Carabus (Greek karabos, 'crab' or 'beetle') + -idae (family suffix)

Example

Pitfall trapping in temperate grasslands often yields high diversity of Carabidae, including abundant Pterostichus and Carabus species that serve as key indicators of habitat disturbance.

Usage Notes

Carabidae is treated as plural in formal usage (the Carabidae are diverse), though singular constructions occur in informal contexts. The common name 'ground beetles' is sometimes restricted to the nominate subfamily Carabinae, but is widely applied to the entire family. Tiger beetles (Cicindelinae) were formerly treated as a separate family Cicindelidae but are now universally placed within Carabidae.
