Erbessa is a genus of moths of the family Notodontidae. It is found in the lowlands of the Neotropics, usually at elevations of 100–500 m (330–1,640 ft), but sometimes as high as 1,800 m (5,900 ft). Moths in this genus are colorful and striking with bright orange-yellow to metallic blue wings. The length of the forewings is 11.0–26.0 mm for males and 12.5–30.0 mm for females. The host ecology of the genus is very poorly known, with hosts documented for only 10 species, but the genus seems to depend on Melastomataceae plants, especially those in the genus Miconia.
