Acentria is a monotypic moth genus of the Crambidae family described by James Francis Stephens in 1829. Its only species, Acentria ephemerella , the watermilfoil moth or water veneer , was described by Michael Denis and Ignaz Schiffermüller in 1775. It is used as an agent of biological pest control against the noxious aquatic plant known as Eurasian watermilfoil ( Myriophyllum spicatum ).
