Calosoma externum, the narrow searcher beetle[1] or churchyard caterpillar hunter, is a species of ground beetle in the subfamily of Carabinae.[2] It was described by Say in 1823.[2] This species is found in most of the United States, where it inhabits fallow fields and may also be found around margins of standing water. The species has also been recorded from the northern shores of Lake Erie in Canada.

Adults reach a length of 28-35 mm and have a black body with bluish reflections on the margins.

Adults prey on caterpillars of Melanoplus, Cirphis, Lachnosterna, Malacosoma and Porthetria species.[3]
