Hygraula nitens, the pond moth or Australian water moth, is a species of moth in the family Crambidae. It was described by Arthur Gardiner Butler in 1880. It is found in New Zealand and most of Australia, including Tasmania.
The wingspan is about 25 mm. The caterpillars of this species live underwater. The larvae feed on Potamogeton crispus and Zostera species. They also feed on other alien macrophytes such as Hydrilla verticillata, Lagarosiphon major, and Ceratophyllum demersum. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Pond Moth is recorded against all the insects logged in Auckland (27 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
