Distribution.

This Palaearctic species is adventive in North America where it ranges from Nova Scotia (Majka et al. 2006: 605) to eastern North Dakota (Cass County, Donald P. Schwert pers. comm. 1989), south along the east coast to New Jersey (Smith 1910: 203, as Tachys frontalis ); also recorded from Missouri (Anonymous 2007). The species is also known from the Vancouver area in southwestern British Columbia (CNC), western Washington (Nelson 1987: 394), and northern Oregon (Westcott et al. 2006: 8). The first inventoried specimen collected on this continent was found in the east prior to 1900 (Hayward 1900: 212, as Tachys frontalis ).
