Nitidula bipunctata has been recorded in Canada from the Yukon and British Columbia east to Québec and Nova Scotia ( McNamara 1991; Majka and Cline 2006), and in the United States from Maine south to Virginia and Kentucky, west to Texas and north to Michigan, Kansas, Iowa, and Minnesota; also on the Pacific coast from Alaska south to Oregon and Idaho ( Parsons 1943; Hatch 1962). Long regarded as an adventive Palearctic species, Majka and Cline (2006) drew attention to the fact that the earliest reports on the continent are from high altitudes in an isolated range of the Rocky Mountains in 1878, a very unlikely location for an introduced species to be found, thus suggesting a possible Holarctic distribution. The species is found on dry carrion ( Dillon and Dillon 1961; Downie and Arnett 1996). In Nova Scotia most specimens were found in association with decomposing pigs ( Sus scrofa Linnaeus ) ( Suidae ) ( Majka and Cline 2006).
