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 →

With luck
About 10% of wildlife watchers report a Pond Moth sighting in Fiordland National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 201 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December and January
In those months about 20% of wildlife watchers report a Pond Moth in Fiordland National Park on a given day, against under 5% in April to November, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Pond Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 parks where we can rate Pond Moth sightings, Fiordland National Park has the highest daily chance: about 10%. Next come Great Otway National Park (Australia, about 10%) and Blue Mountains National Park (Australia, about 10%).

GBIF citizen-science records
It is estimated from how often the Pond Moth is recorded against all the insects logged in Fiordland National Park (15 verified sightings from 2019 to 2026), 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.
