An ermine moth now found commonly in the United States. It was formerly known under the scientific name Atteva punctella. The caterpillars have a wide, light greenish-brown stripe down their backs and several thin, alternating white and olive-green stripes along their sides. Adult wings are orange with clustered white spots surrounded by black.
Like the common name suggests, they are commonly found feeding on or near Ailantus trees. Also commonly found on flowers in meadows and fields.
