Tachys mordax

Tachys mordax is a small ground beetle in the family Carabidae, described by John Lawrence LeConte in 1852. The genus Tachys comprises diminutive, fast-running beetles commonly known as 'tiger beetles' or ground beetles, though Tachys species are typically smaller and less conspicuous than the classic tiger beetles of genus Cicindela. Like other members of its genus, T. mordax is likely adapted to open, sandy or disturbed habitats where it actively pursues small invertebrate prey. The species is recorded from the United States and is part of the diverse North American carabid fauna, though specific ecological details remain poorly documented in published literature.
