With luck
About 10% of wildlife watchers report a Vidler's Alpine sighting in Olympic National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd 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.
July
In that month about 20% of wildlife watchers report a Vidler's Alpine in Olympic National Park on a given day, against under 5% in September to May, the lowest months. That is one of Olympic National Park's driest months, with about 35 mm of rain against 370 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Vidler's Alpine sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Olympic National Park, in our data
Olympic National Park is the only park on Wallace's Line with enough records to rate Vidler's Alpine sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Vidler's Alpine that you can see in Olympic National Park (family Nymphalidae, Brush-footed Butterflies) are Snowberry Checkerspot (about 20%), Pearl Crescent (about 20%) and Hydaspe Fritillary (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vidler's Alpine is recorded against all the insects logged in Olympic National Park (30 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.
