With luck
About 10% of wildlife watchers report a Phoebus Apollo sighting in Denali National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 36 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Phoebus Apollo in Denali National Park on a given day, against under 5% in March–June and September–October, the lowest months. Those are among Denali National Park's wettest months, with about 170 mm of rain a month against 45 mm in April. November to February have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Phoebus Apollo sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Phoebus Apollo is recorded against all the insects logged in Denali National Park (10 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.
