Autographa v-alba is a North American noctuid moth first described by Rodrigues Ottolengui in 1902. It belongs to the subfamily Plusiinae, commonly known as loopers or semiloopers. The species is restricted to montane and foothill regions of western North America, with adults active in mid-summer. It is distinguished by a characteristic white Y-shaped mark on the forewing, referenced in both its scientific and common names.
