Dysstroma truncata

University of Alberta E.H. Strickland Entomological Museum Read more about this collection »

Common NameMarbled Carpet SeasonalityAdults fly in Alberta from late June through late July. IdentificationThis group of Dysstroma, consisting of D. truncata, suspectata, walkerata, and citrata, form a complex of species which are often difficult to distinguish without resorting to examining the genitalic characters. Forewing colouration is variable. Most similar to and difficult to distinguish from D, citrata; D. truncata flies earlier, and has a brighter, more contrasting orange-brown subapical patch, and the brown AM band usually appears as a more well-defined semi-circle at the anal margin - in citrata, this semi-circle is not apparent as the band is more continuous. The North American subspecies is transversata (Kellicott). McDunnough (1946) illustrates the male and female genitalia.

Life History Little data available; the brief information in Forbes (1948) under this species is questionable due to confusion with other species. Adults come to light. Conservation Not of concern. Diet Info Larvae feed on a wide variety of plants, including herbs, shrubs coniferous and deciduous trees. Range YT to Labrador, south to NY and NC in the east (Forbes 1948).
