Smaller than the similar Monopis crocicapitella, golden orange / yellow dorsal streak on forewing, less peppering, more distinctive markings and darker ground colour with dark hindwing not pale grey as on M. crocicapitella.

Larvae feed on woollen materials in outbuildings or out of doors and less often in birds' nests or birds of prey pellets.
