Axia or the "Gold Moths" is a genus of moths whose precise relationships within the Macrolepidoptera[1] are currently uncertain, but they currently represent a superfamily whose nearest relatives include the butterflies, Calliduloidea, Drepanoidea, Geometroidea, Bombycoidea, Mimallonoidea and Lasiocampoidea, and the Noctuoidea. Uniquely, they have a pair of pocket-like organs on the seventh abdominal spiracle of the adult moth which are only possibly sound receptive organs . They are quite large andbrightly coloured moths that occur only in Southern Europe and feed on species of Euphorbia. Sometimes they are attracted to light .One species, Epicimelia theresiae, was formerly included in this genus, but has since been recognized as distinct; it is the only other described species in the family.[2] Shen-Horn Yen and Joël Minet (2007) Cimelioidea: A New Superfamily Name for the Gold Moths (Lepidoptera: Glossata).
