Elophila obliteralis, the waterlily leafcutter moth, is a moth of the Crambidae family. It was described by Francis Walker in 1859. It is native to eastern North America. It is an introduced species in Hawaii and South Africa.[1]

The wingspan is 10–22 mm with the male being smaller than the female. Adults are on wing from May to August in North America.

The larvae feed on a wide range of aquatic plants, including Hydrilla verticillata, Eichhornia crassipes, Pistia stratiotes, Nymphaea and Potamogeton species. At birth, larvae have a longitudinal tracheal system and some long simple hairs but do not later acquire filamentous gills. It forms a case of leaf debris. The larvae are about 9 mm long and have a pale brown head and a dull pallid-green body.
