Systematics
Fairy longhorn moths belong to the superfamily Adeloidea, one of the basal (“monotrysian”) branches of the advanced moth infraorder Heteroneura. By lepidopteran standards, they are thus still rather primitive micromoths. But like other Heteroneura, they already possess the apomorphic sucking proboscis – usually considered a defining feature of Lepidoptera, but the most ancestral moths still live on solid food which they chew. The Adelidae were previously placed as the subfamily Adelinae within the family Incurvariidae.
