This introduced Palearctic species is newly recorded in Nova Scotia (Fig. 1). Bousquet (1991) reported it from New Brunswick. Species of Silvanus are found under the bark of logs and dead trees where they are at least partly fungivorous (Thomas 1993). In Nova Scotia they have most frequently been found in coniferous forests, under the bark of red spruce ( Picea rubens Sarg.) and white pine ( Pinus strobus L.) ( Pinaceae) and on maple ( Acer sp.).
