Calosoma sycophanta (Linnaeus, 1758)

Carabus sycophanta Linnaeus, 1758: 414. Type locality: «Europa» (original citation), restricted to «Sweden» by Lindroth (1961a: 47). One possible syntype in LSL (Lindroth 1957b: 334).

Distribution.

This European species was introduced as early as 1906 in many places in Canada and United States for the biological control of two introduced lymantriids: the gypsy moth, Lymantria dispar (Linnaeus), and the browntail moth, Euproctis chrysorrhoea (Linnaeus). Based on the extensive survey of Schaefer et al. (1999), the species is now established in eastern United States from southern Maine to Maryland and West Virginia, west to western Pennsylvania. The record from “Michigan” (Bousquet and Larochelle 1993: 71) must be in error. There is no confirmation that the species is established on the west coast and the record from “Washington” (Bousquet and Larochelle 1993) should be deleted.
