Bembidion quadrimaculatum oppositum Say View in CoL

BC: Terrace, 6.IV.1923 (Mrs. W.W.H.) [ UBC] .

Holarctic in distribution, B. quadrimaculatum oppositum is known in North America from AB, CO, CT, DC, GA, IA, IL, IN, KS, MA, MB, MD, ME, MI, MN, MO, NB, NC, ND, NE, NF, NH, NJ, NS, NY, OH, ON, PA, PE, PQ, RI, SC, SD, SK, TN, TX, VA, VT, WI and WV (Bousquet and Larochelle 1993). The BC record seems to be the first west of the Rocky Mountains. Along with B. lampros , it is one of the least humidity loving species of Bembidion ( Lindroth 1992) . It has been frequently found on dry barren banks of

fresh water, and also in open, preferably cultivated fields, quite independent of water ( Lindroth 1992). It occurs on slightly moist, clay or claymixed sandy soil with sparse vegetation, allowing complete exposure to the sun ( Lindroth 1986). This species breeds in spring, and hibernates as an adult ( Lindroth 1992). Its wings are fully developed ( Lindroth 1992).
