Hydriomena hemizona
In 3 days ~40% in a week ~60%
Hydriomena hemizona is a species of moth in the family Geometridae. It was first described by Edward Meyrick in 1897. 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.) hemizona. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Hydriomena hemizona is recorded against all the insects logged in Fiordland National Park (29 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.
