Newly recorded in New Brunswick, Nova Scotia, Prince Edward Island, and the Maritime Provinces as a whole ( Fig. 2 ). Adults and larvae of Triplax species feed in soft bracket fungi, particularly Inonotus spp. ( Polyporaceae ) and Pleurotus spp. ( Tricholomataceae ) ( Skelley & McHugh 2002). Specifically, Triplax dissimulator has been recorded from Hypsizygus tessulatus (Bull. ex Fr.) Sing. (Tricholomataceae) and Pleurotus spp. ( Skelley et al. 1991).
