Calosoma sayi, also known as "Say's caterpillar hunter or "Black Caterpillar Hunter",[1] [2] is a species of ground beetle of the subfamily Carabinae.[3] It was described by Dejean in 1826.[3] A large, lustrous black beetle found throughout the United States, its habitat is fields and disturbed areas. About 25mm to 28mm long, its grooved elytra have rows of metallic dots or pits. Said pits are smaller than many Calosoma, and are ruby red. Both larvae and adults prey upon other larvae and pupae, specifically those of grubs, flies, and lepidoptera.[2]
