The Obtectomera is a clade of macro-moths and butterflies, comprising over 100,000 species in at least 12 superfamilies.[1][2] This clade was initially defined by a pupal stage with the four anterior abdominal segments fused and immobile as the sole synapomorphy, but was later revised to include the modification of the dorsal edge of the pulvillus with a protrusion in the adult.[3]
