Dorsal habitus: Fig. 1, Acrotona avia ; Fig. 2, Oligota parva ; Fig. 3, Strigota ambigua ; Fig. 4, Myrmecopora vaga . Oligota parva ( Fig. 2 ) is newly recorded in Canada ( Fig. 12 ). It has been previously recorded from California, Massachusetts, Missouri, and Texas (Moore and Legner 1975). It has been introduced to the western Palearctic and northern Africa and is now widespread there ( Horion 1967 ; Smetana 2004 ). It is found in compost, on dung, in fermenting materials, in old hay and grass, and in other decomposing situations ( Horion 1967 ). The ecology of Oligota species are not well known, however, at least some species prey on mites ( Frank et al. 1992 ). While O. parva has not previously been reported as a beach drift species, all the specimens collected on Prince Edward Island were found in this habitat. One European species, Oligota pusillima Gravenhorst, 1806 has been recorded in decaying seaweed ( Fowler 1888 ; Moore and Legner 1975). Other characteristic beach drift species collected together with O. parva at Launching (PEI), include Atheta acadiensis , Strigota ambigua (see below) [ Staphylinidae ], Hypocaccus fraternus (Say, 1825) [ Histeridae ], Monotoma producta LeConte, 1855 [ Monotomidae ], and Blapstinus metallicus (Fabricius, 1801) [ Tenebrionidae ].
