With luck
About 10% of wildlife watchers report a Common Earl sighting in Doi Inthanon National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st most-seen of the 153 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January–March and May
In those months about 10% of wildlife watchers report a Common Earl in Doi Inthanon National Park on a given day, against under 5% in April and June–December, the lowest months. Those are among Doi Inthanon National Park's driest months, with about 95 mm of rain a month against 340 mm in August.
Between 9 am and noon
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.
5th of 6
Of the 6 parks where we can rate Common Earl sightings, Doi Inthanon National Park ranks 5th at about 10%. The best odds are in Namdapha National Park (India, about 40%), Cuc Phuong National Park (Vietnam, about 30%) and Cat Tien National Park (Vietnam, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Earl is recorded against all the insects logged in Doi Inthanon National Park (5 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.
