The clouded border is a small, unmistakable moth with white wings marked by black or dark brown patches along the edges; the amount and shape of the black varies considerably between individuals, and males usually carry more black than females. It rests with its wings held flat.

Caterpillars feed on aspen, other poplars, sallows, willows, and hazel through summer, and the single yearly generation flies at night from late spring into summer, though it can also be disturbed from low vegetation by day.
