Elaterinae

Elaterinae Sericus honestus (Randall, 1838) NOVA SCOTIA: 65 specimens examined from Colchester, Cumberland, Halifax, Hants, Inverness, and Richmond counties. The earliest record is from 1995 (Colchester Co.: Kemptown, 14.vi.1995, C. Corkum, deciduous forest, flight-intercept trap, NSMC; Nuttby Mt., 14.vi.1995, C. Corkum, deciduous forest, flightintercept trap, NSMC. Newly recorded in Nova Scotia. Collected in both coniferous and deciduous forests of all ages. Sericus incongruus (LeConte, 1853) PRINCE EDWARD ISLAND: Queens Co.: Pinette, 24.vi.2003, C.G. Majka, coastal forest, CGMC. Newly recorded from Prince Edward Island. In Nova Scotia collected in red spruce (Picea rubens Sarg.) and eastern hemlock (Tsuga canadensis (L.) Carr.) forests of all ages. Reported from forested areas in western Canada by Brooks (1960). In some studies (i.e., Boiteau et al. 2000) the Palaearctic species, Sericus brunneus (Linnaeus, 1758), has also been reported in the region. There is continuing uncertainty as to whether S. incongruous and S. brunneus represent distinct species or a single Holarctic species. Pending further investigation we treat all the specimens from the region as the Nearctic S. incongruus. Megapenthes stigmosus (LeConte, 1853) NOVA SCOTIA: Hants Co.: Mount Uniake, 27.viii.2004, D. MacDonald, NSNR. Newly recorded in Nova Scotia. A boreal forest species (Becker 1971); predominantly found in poplar forests and parklands; usually collected on dense undergrowth (Brooks 1960). Agriotes pubescens Melsheimer, 1845 This species was reported from New Brunswick by Bousquet (1991), however, no voucher specimens were located in any collection, nor are there published records from the province. Becker (1956, pp. 69) writes that, "in many collections pubescens is confused with quebecensis " and his accompanying range map shows it occurring east only to southern Québec and western Maine. Accordingly, the species is removed from the faunal list of Nova Scotia. Agriotes quebecensis Brown, 1933 PRINCE EDWARD ISLAND: Queens Co.: Wheatly River, 2.vi.1971, J. MacLeod, on alder, UPEI. Newly recorded from Prince Edward Island. No additional information on bionomics is available. Agriotes sputator (Linnaeus, 1758) NOVA SCOTIA: Digby Co.: Marshalltown, 16.vi.1952, 9.ix.1952, C.J.S. Fox, (4), NSAC. PRINCE EDWARD ISLAND: Queens Co.: Pownal, 19.vi.1997, J.G. Stewart, ACPE; Pownal, 18.vi.2001, M.E. Smith, (8), ACPE. This introduced and invasive Palaearctic species is newly recorded from Prince Edward Island. It was first recorded in North America in New Brunswick in 1939 (Brown 1940). The earliest records from Nova Scotia are from 1952 (see above). Adults are frequently found in pastures and grasslands where the larvae (wireworms) feed on the roots of various species of grasses (Brian 1947). In Nova Scotia the species has attained very high population densities (3 million/acre) in wheat fields; the larvae prefer slightly drier and lighter soils than A. mancus (Say) (Becker 1956). Agriotes stabilis (LeConte, 1853) NOVA SCOTIA: 60 specimens examined from Cape Breton, Colchester, Cumberland, Digby, Guysborough, Halifax, Hants, Lunenburg, Queens, Richmond, and Shelburne counties.

In Nova Scotia found in deciduous, coniferous, mixed forests, and adjacent clearings. Common on undergrowth (especially on wood fern) in birch-poplar stands; the larvae prefer sandy soils where they are predators in the humus layer (Becker 1956).
