A number of species in various familes of moths in Australia have brachypterous females: with either undeveloped or vestigial wings. Female moths have the extra weight burden, over male moths, of the eggs they are to lay. For species in some families this is accommodated by the females being larger than the males, as in Anthela species in ANTHELIDAE, most HEPIALIDAE and LASIOCAMPIDAE, and Lepidoscia species in PSYCHIDAE. But other species, some illustrated here, just save females the trouble of flying by not developing their wings sufficiently:
