Margined white adult butterfly's have medium to small wings that are white, yellow, or orange with variable shaded dark vein patterns visible on the wings against their background color. Summer form is pure white above and below with notable changes in coloration during spring when a black-tipped upper forewing can be observed.
Margined White Butterfly's feed on nectar from flowers of the mustard family and other plants in forests, meadows, deciduous woods, streamsides from Western North America along the coast and in the Rocky Mountains from CA & NM north nearly to Alaska. Southern British Columbia and Alberta south to central California and southern New Mexico; east to eastern Wyoming and eastern Colorado.
This Margined White Butterfly was actively visiting flowers and trees on a warm sunny day when it caught my eye. Once contained for pictures I happily observed the most interesting eyes of this species. A beautiful bright white butterfly to observe from a distance. Close up revealed dark veins of color.
