Rhadine persephone is a rare species of beetle known by the common name Tooth Cave ground beetle. It is endemic to Texas in the United States, where it occurs in a network of caves outside Austin.[1] It is a federally listed endangered species of the United States.
This troglobite is a reddish brown beetle about 7 or 8 millimeters long. Its eyes are rudimentary.[2] It lives on the silt on the cave floors, where it runs around seeking food. It digs up and consumes cricket eggs.[3]
This beetle has been found at 54 locations in karst caves in Travis and Williamson Counties in Texas; three of these locations have since been destroyed.[4] The beetle's survival is threatened by the destruction of its cave habitat, the degradation of the caves by pollution and garbage, and the invasion of fire ants.[3]
