About 30% of wildlife watchers report a Common Earl sighting in Cuc Phuong National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 51st most-seen of the 126 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Common Earl sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 6 parks where we can rate Common Earl sightings, Cuc Phuong National Park ranks 2nd at about 30%. The best odds are in Namdapha National Park (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Common Earl is recorded against all the insects logged in Cuc Phuong National Park (22 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.
