The Twenty-plume Moth is a "micromoth" of the many-plumed moth family . It is found in Europe and has been introduced into North America.
The wingspan is 14–16 mm. Unlike a typical moth, which has two pairs of scaly wings, ''Alucita'' has about twenty thin feathery plumes . It perches with the wings outspread like a fan. The wings have a bold zigzag pattern in white, black and brown, which together with the shiny backward-pointing hairs on each plume make the adult moth distinctive.
