Includes the "Prominents"; medium sized fairly broad bodied moths with long narrow forewings which have a raised tuft of scales on the dorsum, larva often with fleshy dorsal humps, and imagines strongly attracted to light; and the “Kittens”, fluffy white, and black or grey marked moths whose larvae have hind claspers modified into bifid tail appendages with eversible mobile flagella probably acting as deterrent to predation. Pupating in a very tough cocoon incorporating particles of wood and attached to tree bark.
