Ground beetles are a large, cosmopolitan family of beetles, [2] the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. [3] As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga.
Beetles are insects that form the order Coleoptera (/ koʊliːˈɒptərə /), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects.

Anthia (common name saber-toothed ground beetles) is a genus of the ground beetle family (Carabidae) from Africa and Asia. Species of Anthia can spray a jet of formic acid up to 30 centimetres (12 in), which, if not treated, can cause blindness in animals that harass the beetles.
Scarites is a genus of ground beetle native to the Palearctic, the Near East, North America and North Africa, India. There are more than 190 described species in Scarites with more than 55 described species from India. [1] These beetles share physical characteristics of the more tropical stag beetles, but are not closely related.
The American carrion beetle (Necrophila americana, [1] formerly Silpha americana) is a North American beetle of the family Silphidae. It lays its eggs in, and its larvae consume, raw flesh (particularly that of dead animals) and fungi. The larvae and adults also consume fly larvae and the larvae of other carrion beetles that compete for the ...
Metriini. Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound.
Larva. Adults measure approximately 4 cm (1.5 inches), are black with six relatively large, white, dorsal spots (four over the elytra and two on the thorax). Other patterns are possible although the pattern is always symmetrical. The larva has a flattened form, a large head capsule, and prominent mandibles. [1]
