With luck
About 10% of wildlife watchers report a Blue-Spotted Emperor sighting in Doi Inthanon National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 105th most-seen of the 153 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.
June
In that month about 30% of wildlife watchers report a Blue-Spotted Emperor in Doi Inthanon National Park on a given day, against under 5% in July to April, the lowest months. That is one of Doi Inthanon National Park's wettest months, with about 270 mm of rain against 20 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Blue-Spotted Emperor sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Blue-Spotted Emperor sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Blue-Spotted Emperor is recorded against all the insects logged in Doi Inthanon National Park (6 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.
