With luck
About 10% of wildlife watchers report a Common Earl sighting in Khao Yai National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 104th most-seen of the 221 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, 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.
4th of 6

GBIF citizen-science records
It is estimated from how often the Common Earl is recorded against all the insects logged in Khao Yai National Park (8 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.
