Alucita is the largest genus of many-plumed moths (family Alucitidae); it is also the type genus of its family and the disputed superfamily Alucitoidea. This genus occurs almost worldwide and contains about 180 species as of 2011; new species are still being described and discovered regularly. Formerly, many similar moths of superfamilies Alucitoidea, Copromorphoidea and Pterophoroidea were also placed in Alucita.

The genus Alucita was established by Carl Linnaeus in the 1758 10th edition of Systema Naturae as a subgenus of Phalaena, Linné's "wastebin genus" for moths. Johan Christian Fabricius in 1775 seems to have been the first author to consider Alucita a genus in its own right, and it remains so until today. However, some subsequent authors believed Linnaeus' name to be invalid, and established alternative names for this genus, but, while the oldest of these, Pierre André Latreille's Orneodes, was used instead of Alucita for a long time, all these subsequent names are today recognized as junior synonyms.
