Adults fly in Alberta in spring (April through early July).
The genus Anticlea Stephens 1831 belongs in the Lepidoptera family Geometridae, subfamily Larentiinae, Tribe Hydriomenini. The genus contains four North American species and two European species. They are medium-sized moths (approx. 2-3.5 cm wingspan) with strongly banded forewings and lightly marked hindwings. Two species, A. vasiliata Gn. and A. multiferata (Wlk.), occur in Alberta. The European species resemble A. vasiliata, but the small size, mahogany color and striate banding of multiferata is be divergent from the other members of the genus.
Anticlea overwinter in the pupal stage (Wagner, 2001), and adults, which come to light, are on the wing in spring and early summer. The known host plants are all Rosaeace, in particular Rosa sp. The larvae are solitary defoliators. The larvae of A. vasiliata is described and illustrated in color in Wagner, 2001.
Relatively common, widespread species; no concerns.
European species feed on Rosa sp.; no North American data except that in the lab they have been reared on blackberry (Rubus; Rosacea) Wagner, 2001).
Two species are widespread in Europe. Two of the four North American species are widespread in the eastern hardwood and boreal forests, from the southeastern states to Alaska; the other two are apparently restricted to the American west. A.vasitiata and A. multiferata occur widely in the parklands and boreal forests of Alberta.
