Yponomeutoidea is a superfamily of ermine moths and relatives. There are about 1,800 species of Yponomeutoids worldwide, most of them known to come from temperate regions. This superfamily is one of the earliest groups to evolve external feeding and to colonize herbs in addition to shrubs and trees.
