Carabus is a genus of beetles in the family Carabidae, [2] and was first described in 1758 by Carl Linnaeus. [2] [3]
The genus is highly diverse with 94 subgenera, over 900 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. [4] [5] [6] The vast majority are native to the Palearctic, but 16 Nearctic species are also known. [4] [6] Carabus species are 12–50 mm (0.47–1.97 in) long, and most species are wingless and often very colourful. [4] These are nocturnal, predatory beetles that feed on snails, earthworms, and caterpillars. [4] [7] Most Carabus species were thought to have inhabited the Eurasian forest, but their low dispersal abilities altered the distribution of lineages within the genus. [4]
Adult Carabus feed on both small live and dead animals such as slugs, snails, earthworms, and insects in all stages, sometimes dead vertebrates. The ways of feeding on snails are different for their adaptations, as macrocephalic beetles feed on snails by crushing the snail shell, and stenocephalic beetles feed on snails by inserting their heads into the snail shell.
