Product Code Database
The Obtectomera is a clade of macro-moths and butterflies, comprising over 100,000 species in at least 12 superfamilies. 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 Pulvilli with a protrusion in the adult.
Some other superfamilies are sometimes included:
The macroheteroceran superfamilies were previously place in the Macrolepidoptera, but recent molecular studies have failed to recover the Macrolepidoptera as a monophyletic group. The latter grouping also included true butterflies (Papilionoidea), New World butterfly-moths (Hedylidae), Old World butterfly-moths (Calliduloidea), and European gold moths (Axioidea).
