Gelechioidea
curved-horn moths, gelechioid moths, case-bearers and twirler moths
Gelechioidea is a large superfamily of micromoths within Lepidoptera, containing case-bearers, twirler moths, and relatives. It comprises approximately 16,250 described species across about 1,425 genera, though estimates suggest only 25% of actual diversity has been documented, potentially making it one of the largest superfamilies of Lepidoptera. The superfamily represents one of the basal lineages of the Ditrysia. Classification remains disputed, with family-level arrangements varying between 16 and 21 families depending on morphological versus molecular phylogenetic approaches.
