Distribution. USA; Michigan; Canada: Alberta; Iceland, British Isles, Netherlands, Belgium, Germany, Austria, Switzerland, Italy (type locality); Poland; former USSR, including Western Siberia; Iran (beehives); China: Yunnan Prov.; Australia (Gu et al., 1987; Richards 1976; Mosaddegh, 1997; Wallace and Holm, 1985).

Biology. Parasitus fimetorum is a common inhabitant of compost, rotting vegetation, manure, dung, and subterranean nests of small mammals, and also occasionally bumblebee, bird nests, and beehives. Deutonymphs are phoretic on coprophagous and necrophagous beetles, Aphodius, Geotrupes (Coleoptera: Scarabaidae), Nicrophorus (Silphidae), and Atholus (Histeridae). In the United States, Canada, and Europe, this species was found in bumbleebee nests, but not on the bees. Thus, it likely does not have any specific relationships to bumblebees (Hyatt, 1980; Richards, 1976).
