Both fore- and hind-wings consist of about six rigid spines, from which radiate flexible bristles creating a structure similar to a bird's feather.

Here, they are united in superfamily Alucitoidea with the Tineodidae, a diverse group of numerous small genera with about 20 species all together.

In any case, the similar-looking plume moths (Pterophoroidea) are widely held to be very close, if not the closest living relatives of the Alucitoidea.

In this Alucitoidea do not exist; Alucitidae and Tineodidae are assigned to different (but still most closely related) superfamilies.

In the treatment here, the Copromorphoidea are presumed to be the most advanced of these lineages of small but fairly "modern" moths, while the Alucitoidea and Pterophoroidea are more primitive.
