Panthea virginarius
In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report a Western Panthea Moth sighting in Olympic National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 162nd most-seen of the 207 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Western Panthea Moth in Olympic National Park on a given day, against under 5% in September to July, the lowest months. That is one of Olympic National Park's driest months, with about 45 mm of rain against 370 mm in November.
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.
3rd of 3
Of the 3 parks where we can rate Western Panthea Moth sightings, Olympic National Park ranks 3rd at under 5%. The best odds are in Pacific Rim National Park Reserve (Canada, about 10%) and Great Bear Rainforest (Canada, about 10%).
Same family: Noctuidae
The closest relatives of the Western Panthea Moth that you can see in Olympic National Park (family Noctuidae, Cutworm Moths and Allies) are Large Gray Dagger (about 10%), MacCulloch's Forester Moth (about 10%) and Large Yellow Underwing (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 Olympic National Park (6 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.
