(Nymphalis l-album)
Butterfly populations are a very good indicator of the health of an area's ecosystem !!
  Nymphalis l-album is found in southeast Alaska and Canada south in the mountains to Montana and Wyoming;,east across southern Canada and the northern United States to New England. Also south to North Carolina and Missouri. Rare migrants reach to Newfoundland, Nebraska, and Florida.
   They are seen in deciduous and coniferous forest in a wide range over the Northern Hemisphere. 
    There is a short tail present on each hindwing. The dorsal side of the wings is orange brown with scattered dark spots and a patch of solid, darker color near the wing base. There is one white spot at the forward edge of each wing. The ventral side of the wings is gray brown, mottled and darker toward the center. There is a small, white mark in the center of each hindwing.
   They are very strong, powerful flyers with a single brood that is on wing from July to November.
   They have a relatively long lifespan, for a butterfly, of approx. 10 monhs, which can be attributed, in part, to their diet, which gives them more nutrients than many species, whose lifespans tend to be from a few days to a month or two.
   * As members of the Brush Footed (Nymphalidae)
family, they use their shorter pair of front legs for food tasting, and their two pairs of longer rear legs for propulsion.

The single biggest threat to butterfly survival is habitat destruction!!
