Panthea virginarius
In 3 days ~20% in a week ~40%
Panthea virginarius, the Cascades panthea, is a moth of the family Noctuidae. It is mainly found west and north of the Great Basin, from the coast of southern California northward to the Queen Charlotte Islands of British Columbia and the Alaskan Panhandle, eastward to central California, northern Nevada, Idaho, north-western Wyoming, western Montana, and south-western Alberta. A disjunct population is found in the Cypress Hills of Alberta and Saskatchewan.
The species is highly variable in both size and colour; the angelica and portlandia forms for example were considered separate species up to 2009. The larvae feed on Pseudotsuga menziesii and other conifers. Wikipedia →

With luck
About 10% of wildlife watchers report a Western Panthea Moth sighting in Great Bear Rainforest on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 235 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April, June–July and September–October
In those months about 10% of wildlife watchers report a Western Panthea Moth in Great Bear Rainforest on a given day, against under 5% in May, August and November–March, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Western Panthea Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Western Panthea Moth sightings, Great Bear Rainforest ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Pacific Rim National Park Reserve (Canada, about 10%).
Same family: Noctuidae
The closest relatives of the Western Panthea 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 Western Panthea Moth is recorded against all the insects logged in Great Bear Rainforest (27 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.
