Stenoporpia pulmonaria

SeasonalityAdults fly primarily in August. IdentificationThe wing colour and pattern resembles tree bark; forewing grey with fine, dark speckling and a prominent black PM line on both wings; AM line fainter. Discal spot and median line obscure. Male antennae conspicuously plumose. Similar to Iridopsis larvaria and Stenoporpia separataria: I. larvaria has a less elongated forewing shape and a broad dark band basal to black AM line which is faint or absent in pulmonaria. In Alberta, pulmonaria occurs only in the mountains from the Bow Valley south, while larvaria is widespread; for genitalic differences see McGuffin 1977). S. separataria has a more crenulate, irregular PM line than pulmonaria; uncertain identifications should be verified through genitalic dissection see McGuffin (1977). Both the larvae and adults of pulmonaria have often been confused with those of Anavitrinella pampinaria, but the adults of pampinaria have short male antennal pectinations and a light contrasting band at the base of the abdomen.

Life History A brief description of the mature larva (based on preserved specimens) and pupa is given by McGuffin (1977). Grown larvae are mimics of conifer twigs, and overwinter half-grown (Duncan 2003). Conservation Not of concern. Diet Info Larvae feed primarily on Douglas-fir (Pseudotsuga menziesii), and occasionally other conifers (McGuffin 1977). Range A western cordilleran species, found from Alaska to California, east to southwest Alberta and Wyoming (McGuffin 1977).
