Rare
Under 5% of wildlife watchers report a Dyar's Looper Moth sighting in Olympic National Park on a given day, based on 12 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 and September
In those months about 10% of wildlife watchers report a Dyar's Looper Moth in Olympic National Park on a given day, against under 5% in October to July, the lowest months. Those are among Olympic National Park's driest months, with about 85 mm of rain a month against 370 mm in November.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dyar's Looper Moth sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Dyar's Looper Moth sightings, Olympic National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Great Bear Rainforest (Canada, under 5%).
Same family: Geometridae
The closest relatives of the Dyar's Looper Moth 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-Marked Angle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dyar's Looper Moth is recorded against all the insects logged in Olympic National Park (12 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.
