Hydriomena deltoidata
In 3 days ~40% in a week ~60%
Hydriomena deltoidata is a species of moth in the family Geometridae. It was first described by Francis Walker in 1862. 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.) deltoidata. The adults of this moth are known to pollinate Dracophyllum acerosum and Leptospermum scoparium. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dark-Banded Carpet Moth is recorded against all the insects logged in Rakiura National Park (13 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.
