SeasonalityAlberta flight dates range from late May to mid June. IdentificationBrown-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.
