Stilbus apicalis is newly recorded in Atlantic Canada ( Fig. 3 ). The species has previously been recorded in eastern North America from Ontario and Maine, south to Florida, and west to Louisiana, Kansas, and Illinois; and in the west from British Columbia south through Idaho to California ( Leng 1920 ; Campbell 1991 ; Downie and Arnett 1996 ; Chandler 2001 ; Gimmel 2008 ). Little is known about its bionomics except that individuals have been collected by sweeping grasses ( Steiner 1984 ), a habitat and collection mode consistent with most of the specimens collected in Atlantic Canada . Specimens are also commonly collected at lights ( White 1983 ). Dearborn and Donahue (1993) reported individuals from spruce ( Picea sp.) in Chesuncook and Augusta, Maine. Steiner (1984) noted that populations are almost exclusively comprised of females, and considered that it is likely a surface feeding, mold grazing, facultatively parthenogenic species. Th e precise hosts of S. apicalis are unknown although some adults were found on an unidentified smut growing on panic grass, P. dichotomiflorum ( Steiner 1984 ) .
