The West Coast Lady's numbers vary dramatically from year to year, but it does not undergo the massive emigrations of the Painted Lady. Its cold tolerance may be in between that of the other ladies: it can withstand moderate winters but not frigid conditions. The West Coast Lady probably travels eastward from the coast in late summer, appearing in the Rockies in the fall. Formerly V. carye.
