Hydriomena rixata
In 3 days ~20% in a week ~50%
Hydriomena rixata is a species of moth in the family Geometridae. It was first described in 1875. This species is endemic to New Zealand. The classification of New Zealand endemic moths within the genus Hydriomena is regarded as unsatisfactory and in need of revision. As such this species is currently also known as Hydriomena (s.l.) rixata. The adults of this moth are known to pollinate Dracophyllum acerosum.
Adults are attracted to light and have been collected via a mercury vapour light trap. Wikipedia →

With luck
About 10% of wildlife watchers report a Hydriomena rixata sighting in Fiordland National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 88th most-seen of the 201 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Hydriomena rixata in Fiordland National Park on a given day, against under 5% in March to November, the lowest months.

Only Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate Hydriomena rixata sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Hydriomena rixata is recorded against all the insects logged in Fiordland National Park (12 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.
