• Lebia subgrandis

  Lebia subgrandis is a ground beetle in the family Carabidae, native to Mexico and found in North America. This species has been investigated as a potential biological control agent for the Colorado Potato Beetle (Leptinotarsa decemlineata). Adults are generalist predators of CPB eggs and early instar larvae, while first instar larvae are specialized ectoparasites of CPB prepupae and pupae. The species exhibits a notably narrow host range, refusing alternative prey even when starved.
