Crocidosema is a genus of tortrix moths (family Tortricidae) belonging to the tribe Eucosmini of subfamily Olethreutinae. They are found mostly in the Southern Hemisphere, being especially common in the Neotropics. But some occur elsewhere, such as on the Hawaiian Islands.

At least some of them can be recognized by their wing veins. In the hindwings, vein 3 and 4 originate from a common stalk, and are approached by the fifth vein at its end. In the forewings, veins 4-6 converge at the termen.

These moths are mostly small and inconspicuous. But C. plebejana is an occasional pest of cotton (and some other mostly malvaceous plants) and has become widely distributed by trade in agricultural produce, while the lantana flower-cluster moth (C. lantana) is employed in Lantana biocontrol and has been deliberately introduced to some locations.
