Rare
Under 5% of wildlife watchers report a Western Catoptria sighting in Great Bear Rainforest on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 178th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Western Catoptria in Great Bear Rainforest on a given day, against under 5% in August to June, the lowest months. That is one of Great Bear Rainforest's driest months, with about 120 mm of rain against 480 mm in November.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Western Catoptria sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Great Bear Rainforest, in our data
Great Bear Rainforest is the only park on Wallace's Line with enough records to rate Western Catoptria sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Western Catoptria that you can see in Great Bear Rainforest (order Lepidoptera, Butterflies and Moths) are Spotted Tussock Moth (about 20%), Gaultheria Leafminer Moth (about 20%) and Silver-Spotted Tiger Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Catoptria is recorded against all the insects logged in Great Bear Rainforest (8 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.
