With luck
About 10% of wildlife watchers report a Clematis Triangle sighting in Egmont National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 44th most-seen of the 191 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January, March and October–November
In those months about 20% of wildlife watchers report a Clematis Triangle in Egmont National Park on a given day, against under 5% in April–September and December, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Clematis Triangle sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Clematis Triangle sightings, Egmont National Park has the highest daily chance: about 10%. Next come Rakiura National Park (New Zealand, about 10%).

GBIF citizen-science records
It is estimated from how often the Clematis Triangle is recorded against all the insects logged in Egmont 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.
