Carabus is a genus of beetles in family Carabidae. The genus is highly diverse with 94 subgenera, 897 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 11 Nearctic species are also known. Carabus spp. are 12–50 mm (0.47–1.97 in) long, and most species are wingless and often very colourful. These are nocturnal, predatory beetles that feed on snails, earthworms, and caterpillars. Most Carabus species were thought to have inhabited the Eurasian forest, but the species' low dispersal abilities altered the distribution of lineages within the genus.
Zabrus is a genus of ground beetles. They are, unusually for ground beetles, omnivores or even herbivores, and Zabrus tenebrioides can become a pest in cereal fields.
Pterostichus is a very large genus of ground beetles with a Holarctic distribution in the subfamily Harpalinae. It has over 1,200 species. The beetles are predatory, but sometimes feed on strawberries. They can be found under rocks and prefer slightly moist, sandy soil although preferences differ between species.
Gyrinus is a genus of small aquatic whirligig beetles in the family Gyrinidae native to the Palearctic, the Near East, the Nearctic, North Africa, Asia and Australia.
Omophron is a genus of ground beetle (Carabidae), the only extant genus in the subfamily Omophroninae. It is mostly distributed in the Northern Hemisphere with the southern border running through Guatemala and Hispaniola in Americas, South Africa and Madagascar in Africa, Malaysia and Philippines in Asia.
Acmaeodera is a genus of beetles in the family Buprestidae, a group of metallic wood-boring beetles favored by insect collectors. Whereas most beetles including most buprestids fly with their elytra held out and vibrating their hindwings to give lift and thrust, Acmaedodera, however, fly with their hind wings only — the elytra are fused down the center and form a shield over the insect's abdomen, even during flight. This fact, combined with the banding across the abdomen which is common in this family, gives many of them a distinct wasp-like appearance when in flight. Several are therefore considered hymenopteran mimics.
Acinopus is a genus of beetles in the family Carabidae, containing the following species:
Athous is a genus of click beetles belonging to the family Elateridae.
Cychrini is a tribe of ground beetles in the family Carabidae. There are about 6 genera and more than 300 described species in Cychrini.
Harpalini is a tribe of a diverse group of ground beetles belonging to the subfamily Harpalinae within the broader family Carabidae. The tribe contains more than 2500 species.
Scaphinotus petersi is a species of ground beetle in the family Carabidae. It is found in North America.
Callisthenes is a genus of black searcher beetle in the family of beetles known as Carabidae. There are at least 50 described species in Callisthenes.
Harpalitae is a supertribe of ground beetles in the family Carabidae. There are at least 90 genera and 460 described species in Harpalitae.
Scaphinotus snowi is a species of ground beetle in the family Carabidae. It is found in North America.
Scaphinotus elevatus, the eastern snail eater, is a species of ground beetle in the family Carabidae. It is found in North America.
Scaphinotus debilis is a species of ground beetle in the family Carabidae. It is found in North America.
Ampedus is a genus of click beetles in the family Elateridae. There are currently 461 recognized species of Ampedus beetles. It has a cosmopolitan distribution, but is found mostly in the Holarctic region, primarily in North America, Europe, and Asia. The oldest known fossil from this genus was found in Eocene Baltic amber, estimated to be from 38.0–33.9 million years ago.
