With luck
About 10% of wildlife watchers report a Clossiana astarte sighting in Jasper National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 63rd most-seen of the 88 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 Clossiana astarte in Jasper National Park on a given day, against under 5% in September to May, the lowest months. Those are among Jasper National Park's wettest months, with about 110 mm of rain a month against 55 mm in April.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Clossiana astarte sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Jasper National Park, in our data
Jasper National Park is the only park on Wallace's Line with enough records to rate Clossiana astarte sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Clossiana astarte is recorded against all the insects logged in Jasper National Park (7 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.
