Rare
Under 5% of wildlife watchers report a Girdler Moth sighting in Great Bear Rainforest on a given day, based on 7 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.
June and September
In those months about 10% of wildlife watchers report a Girdler Moth in Great Bear Rainforest on a given day, against under 5% in July–August and October–May, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Girdler Moth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Great Bear Rainforest, in our data
Great Bear Rainforest is the only park on Wallace's Line with enough records to rate Girdler Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Girdler Moth that you can see in Great Bear Rainforest (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 20%), Large Gray Dagger (about 10%) and American Angle Shades (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Girdler Moth is recorded against all the insects logged in Great Bear Rainforest (7 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.
