With luck
About 10% of wildlife watchers report a Pale-Marked Angle sighting in Olympic National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th most-seen of the 207 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.
June to August
In those months about 10% of wildlife watchers report a Pale-Marked Angle in Olympic National Park on a given day, against under 5% in September to May, the lowest months. Those are among Olympic National Park's driest months, with about 55 mm of rain a month against 370 mm in November.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Pale-Marked Angle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 3 parks where we can rate Pale-Marked Angle sightings, Olympic National Park 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: Geometridae
The closest relatives of the Pale-Marked Angle that you can see in Olympic National Park (family Geometridae, Geometer Moths) are Western White-Ribboned Carpet (about 10%), Gray Spruce Looper Moth (about 10%) and Pale Beauty (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pale-Marked Angle is recorded against all the insects logged in Olympic National Park (20 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.
