This common Holarctic species is found under bark of dead trees, usually coniferous species ( Smetana 1971a ). In New Brunswick, most specimens were found under bark of conifer logs or stumps and some under bark of hardwoods. Adults were also commonly captured in Lindgren funnel traps. Adults were collected in April, May, June, July, and August. Distribution in Canada and Alaska. AK, YT, NT, BC, AB, SK, MB, ON, QC, NB, NS ( Smetana 1971a ; Bishop et al. 2009 ).
