• Acentria

  watermilfoil moth, water veneer

  Acentria is a monotypic moth genus in the family Crambidae containing a single species, Acentria ephemerella. The genus is notable for extreme sexual dimorphism in wing development and for having the only known fully aquatic adult female moths. Most females are flightless with rudimentary wings and spend their entire lives underwater, while males are fully winged and terrestrial. The species is native to Europe and has been introduced to North America.
