|scientific name Metarranthis warnerae |
Mesic deciduous and mixedwood boreal forest.
Alberta flight dates range from late May to mid June.
Brown-grey ground colour with dark AM and PM lines, PM line bordered proximally with dark brown. Discal spot black. Very similar to M. duaria, but lacks the reddish brown overtones of that species. M. warnerae also has a smoother, straighter PM line than M. duaria. McGuffin (1987) states that the presence of dark shading on the inside of the PM line distinguishes warnerae from duaria, but this trait is found in both species in Alberta specimens.
McGuffin (1987) indicates that this species is diurnal, but adults also come to lights. Virtually no life history information is available for this species. It is very rare in Alberta.
In Alberta, known only from a few sites in the Edmonton region. Rare.
Larvae feed on cherry, dogwood and willows (Prunus, Cornus and Salix spp.) (McGuffin 1987).
Central Alberta east to New Brunswick, IN, and NY (McGuffin 1987).
