Adults of Mycetoporus rugosus have been collected from a wide variety of moist (often deep and moldy) litter and moss, including both decidu ous and conifer litter of various species in forested habitats, as well as lake, stream, and river margins ( Campbell 1991 ). New Brunswick specimens were collected from similar habitats, most frequently from moss and litter near brooks in old-growth eastern white cedar swamps. Adults were also collected from drift material and oak leaf litter along a lakeshore and from sphagnum in a black spruce forest. Adults from New Brunswick were collected during May and June.
