Other: The Linden Looper is found across Canada and as far north as Ft. McMurray west to Peace River in Alberta.  It can be locally common, but rarely causes any significant economic damage.  Male moths are light tan brown with wavy darker brown markings. The males are attracted to light at night. Females are wingless and have black markings on a white background.  In Alberta the adults emerge in mid-September to early October.  After mating the females lay eggs which over winter, with the larva hatching in the spring.  (Philip & Mengersen, 1989, Covell, 1984))
