Collection and habitat data.

Mycetophagus pluripunctatus was found in mature and old hardwood forests with sugar maple, American beech, white ash, and butternut ( Juglans cinerea L.), an old-growth northern hardwood forest with sugar maple and yellow birch ( Betula alleghaniensis Britt.), an old red oak forest, a mature (110-year-old) red spruce forest ( Picea rubens Sarg.), an old-growth white spruce ( Picea glauca (Moench) Voss) and balsam fir forest, and an old red pine forest. Adults were found in or on fleshy (bracket, shelf) polypore fungi on standing, dead American beech trees and logs, and on partially dried Pleurotus sp. on a dead, standing sugar maple. One individual was collected from a decaying Climacodon septentrionale on dead, standing yellow birch in a clearcut. Majka (2010) reported other fungal associations with this species. Adults were also captured in Lindgren funnel traps at several sites in New Brunswick. Adults were captured during April, May, June, July, and August.

Distribution in Canada and Alaska.

AB, MB, ON, QC, NB, NS ( Bousquet 1991; Bishop et al. 2009; Majka 2010). Majka (2010) newly recorded this species from New Brunswick based on a specimen collected by R. Migneault in Edmundston (Madawaska Co.). This species is widespread in the province.
