Natural History: Chittenden (1890) reported that it has been collected from dead oak ( Quercus ), dead maple ( Acer ) in New York and milled birch ( Betula ) in Maine; infestations not noted. Bøving & Champlain (1920) reported that adults were collected from spruce ( Picea ) infested with the spruce bark beetle ( Dendroctonus piceaperda Hopkins ) in Maine and with the scolytine Polygraphus in West Virginia. They also reported collections from a decaying wound in a living beech ( Fagus ) in WV and under bark of dead white pine ( Pinus strobus ) in New Hampshire. Knull (1951) reported that adults are diurnal and occur under bark or at the bases of dead trees with wood boring insect infestations in Ohio. Gosling (1980) reported collecting it from oak ( Quercus ) logs in Michigan. Mawdsley (1999) reported observing adults on recently dead or dying trunks or recently felled logs of eastern white pine and that adults overwinter at the bases of dead trees beneath the bark in frass. Mawdsley (1999) reported collecting it from beneath the bark of large, dead beech ( Fagus ), black cherry ( Prunus serotina ), eastern hemlock ( Tsuga canadensis ) and eastern white pine ( Pinus strobus ). Ryall and Fahrig (2005) reported collecting adults from red pine ( Pinus resinosa ) infested with the pine engraver ( Ips pini (Say)) . Majka (2006) added that in Nova Scotia, it is associated with scolytine galleries in red spruce ( Picea rubens ) and eastern hemlock ( Tsuga canadensis ). Dorshorst & Young (2008) reported collections from white oak ( Quercus alba ) and dead northern pin oak ( Q. ellipsoidalis ) and northern red oak ( Q. rubra ) and associations with oak sap flows and shelf fungi on dead yellow birch ( Betula alleghaniensis ) in Wisconsin. They also reported observing it “feeding on leiodids and sphindids within the fruiting structures of myxomycetes under the bark of standing, dead hardwood and Pinus resinosa Aiton trees” and that Lindgren funnel traps were the most frequent collecting method. While working in the eastern part of the northern boreal forest in Canada, Bouchard and Hebert (2016) only found this species in patches of forest larger than 50 ha.
