Tetracha carolina is a large species of nocturnal tiger beetle. Its range is primarily south of Maryland, though it is recorded from Worcester Co. This species flies well, and is known to disperse outside of its range. Perhaps the Maryland record represents a vagrant beetle, but the possibility exists that it is at the extreme northern extent of its range. T. carolina appears to prefer habitats near water, like river floodplains, where they may be abundant. They are also known from many other habitats, including coastal marshes, mudflats, agricultural fields, and even suburban developments.


T. carolina can be distinguished from the larger T. virginica, which ranges widely in Maryland, by noting the bright cream-colored apical lunules at the ends of the elytra, which virginica lacks.

There are 2 records in the project database.
