Catops basilaris was reported by Peck and Cook (2002) from Labrador, Newfoundland, New Brunswick, and Nova Scotia including Cape Breton Island ( Fig. 11). It is the most widespread and frequently collected species of Catops in North America, primarily collected in forested environments at carrion, but also occasionally on decaying mushrooms, in forest litter, in mammal and wasp nests, and on owl pellets. It is found in deciduous, mixed, and coniferous forests and Sphagnum bog habitats ( Peck and Cook 2002). In Nova Scotia, specimens have been collected in coniferous, deciduous, mixed, and coastal forests.
