Gelechioidea is the superfamily of moths that includes case bearers and relatives. Gelechioidea is a large and poorly understood superfamily belonging to the order Lepidoptera, (Moths and Butterflies). Gelechioidea is composed of approximately 1,425 genera and 16,250 species (Hodges, 1998). Hodges estimates that only 25% of the species diversity of Gelechioidea has been described. If this estimate is accurate, Gelechioidea will be one of the largest superfamilies of Lepidoptera. SourcesFirefly… (More on Gelechioidea)
