Sericoderus lateralis (Gyllenhal)

In Canada recorded from British Columbia and Québec ( Campbell 1991); in the U.S.A. scattered records from Maine ( Chandler 2001) and Massachusetts south to Florida and west to Washington (Downie and Arnett 1996). This is an adventive Palearctic species, which in Europe is broadly distributed across the continent ( Freude et al. 1971). Bowestead and Leschen (2002) report that members of Sericoderus feed on Hypomycetes and Zygomycetes and can be found in bird and caterpillar nests. In Nova Scotia found feeding on moldy corncobs in a compost heap. In Europe it occurs, often in very large numbers, on moldy plant remains in warm places, especially garden compost and grass cuttings ( Bowestead 1999).

This species was first reported in North America in Oregon in 1949 (as Arthrolips decolor (LeConte)) in the nest of a woodrat (Walters and Roth 1950). Meagre past collecting for this family makes it difficult to establish if this species has recently spread to the province or if it has existed undetected for some time. Newly recorded in Nova Scotia.
