Although Bousquet (1991) listed this species from both New Brunswick and Nova Scotia, Muona (2000) did not record it from either province and there are no specimens in the CNC or in any other collection examined. Thus the above records establish the species' presence in both provinces. It is additionally newly recorded from Prince Edward Island ( Fig. 4 ). Reared from yellow birch ( Betula allagheniensis Britt. ) ( Betulaceae ) and found associated with red spruce ( Picea rubens ) and American beech ( Fagus grandifolia ) ( Muona 2000). Restricted in its distribution to northeastern North America ( Muona 2000) .
