White Satin Moth (Leucoma salicis)

The white satin moth of the Erebidae family gets its name because of its silvery-white body and satiny wings. It has a widespread distribution spreading throughout Europe, and parts of Asia, up to Japan. In North America it was introduced in the 1920s, and eventually it populated in most counties of the U.S.
