Status
"This species is one of only two intentionally introduced carabids in North America that became established on this continent, the other one being Carabus auratus. These species were introduced for the biological control of the gypsy moth, Lymantria dispar, and the browntail moth, Euproctis chrysorrhoea. Since its release in the vicinity of Boston in 1906-1907, C. sycophanta has spread to southern Maine and to West Virginia" (Bousquet, 2012).

Description
[edit]Calosoma sycophanta can reach a length of about 21–35 millimetres (0.83–1.38 in). This large ground beetle has characteristic metallic bright green elytra, while scutellum is metallic bluish. The head is black. These colours have iridescent shades that change (green, blue, bronze, copper, gold black) according to the direction and quality of light. Pronotum is transverse shaped, posteriorly sharply narrowed, wrinkled and punctured. Elytra are flattened with clearly visible punctures in the striae.[2]
Behavior
[edit]This ground beetle is a voracious consumer of caterpillars (especially Lymantria dispar, Thaumetopoea processionea, Thaumetopoea pityocampa and Euproctis chrysorrhoea) during both its larval stage and as an adult.[3][4][5][6]
As a predator the species has been researched for the effect of its predation upon the caterpillars with microsporidian pathogens, finding a preference for Vairimorpha disparis infected larva.[7]
Distribution
[edit]This species is native to Europe. It is present in most European countries, in the eastern Palearctic realm, in the Nearctic realm, in the Near East, and in North Africa.[8] In 1905 it was imported to New England for control of the gypsy moth.[3]
