Explanation of Names
This subspecies, along with several others, is often separated out as part of a species - Anthocharis julia - separate from A. sara.
The only Orangetip found in its area; so, easily recognized, with white to yellowish background color, bright orange toward front wing tip, and with greenish marbling under the hind wings. Marbles (genus Euchloe) are most similar, but lack the orange, and are rarely so yellow in color as many female A. sara. Males are usually white, females more often distinctly yellowish. Females have less orange and more dark pattern on the front wing tips.
Oregon - east of the Cascades, north into British Columbia (?Alberta), and east to western Montana and Wyoming.
This subspecies tends to have the dark pattern somewhat reduced and washed out as compared to other subspecies. The very similar, but even paler subspecies browningi replaces this subspecies southward in northern Utah. Other subspecies replace it to the south, east and west.
