Bembidion
Bembidion is the largest genus of ground beetles in the family Carabidae by number of species. All species are small, measuring less than 7.5 mm, and are characterized by rapid movement. The genus exhibits a biantitropical distribution pattern, occurring in temperate regions of both the Northern and Southern Hemispheres but absent from tropical zones. Taxonomic subdivision of the genus remains unresolved, with multiple attempts to split it into smaller genera failing to achieve general acceptance.
