Bembidion properans (Stephens, 1828)

NOVA SCOTIA: Halifax Co.: Halifax, 1.vii.1942, M. Mosher, carrot row, (4, ACNS); Kings Co.: Kentville, 27.v–7.vi.1949 and 28.vi.1949, C.R. MacLellan, insecticide plots, (2, ACNS); Lunenburg Co.: Lunenburg, 16.ix.1954, C.J.S. Fox, (1, ACNS).

This species was first reported in North America by Lindroth (1954) on the basis of a single specimen collected by W.J. Brown in 1947 in Dartmouth and subsequent specimens collected by C.H. Lindroth in 1951 in Halifax, Riversdale, and Crescent Beach, Nova Scotia, and D.C. Ferguson in 1952 in Halifax (NSMC). The above specimens, collected in 1942 in Halifax, establish a new and earlier timeline for this species on the continent. It is also noteworthy that specimens were collected so soon afterwards in Kings (1949) and Lunenburg (1954) counties, indicating either rapid dispersal or multiple points of entry. The species is found in vacant lots, edges of fields, roadsides, sand pits, and open forests; primarily on open, moderately moist soil ( Larochelle & Larivière 2003).
