Cook, sand dunes, pitfall trap, (5, JCC). PRINCE EDWARD ISLAND : Kings Co.: Launching, 26.VIII.2003 , C.G. Majka, coastal barrier beach: beneath coastline drift at the top of the littoral zone, (4, CGMC). Strigota ambigua ( Fig 3 .) is newly recorded in Canada ( Fig. 12 ). It is widespread in the United States across a band from Connecticut , New York and New Jersey , south to North Carolina , west through Iowa , Missouri , Kansas , and Texas , to Colorado , New Mexico , Nevada , and California on the Pacific coast (Gusarov 2003). Almost nothing is known of the bionomics of this species. Gusarov ( 2001 -2003) recorded it from along riverbanks and in flood refuse. All the specimens found in the Maritime Provinces have been in sand dune and beach-drift environments. At Beaver River, NS other characteristic coastline species collected with S. ambigua include Hypocaccus fraternus , Stenus erythropus, Aegialia opifex Horn, 1887, and Blapstinus metallicus .
