Description

Wingspan about 11mm. The females of this species have their antennae thickened with elongated scales for about three-fifths of their length, creating a noticeably 'shaggy' appearance. Males have slightly thickened antennae over three fifths, though with recumbent scales. Both sexes sport a tuft of erect scales on the head, and the forewing has some raised scales, though not so noticeable as those on O. taurella.
