With luck
About 10% of wildlife watchers report a Spotted Sawtooth sighting in Doi Inthanon National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th 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 60%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Spotted Sawtooth in Doi Inthanon National Park on a given day, against under 5% in May–September and December–January, the lowest months. That is one of Doi Inthanon National Park's driest months, with about 35 mm of rain against 340 mm in August.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Spotted Sawtooth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5

GBIF citizen-science records
It is estimated from how often the Spotted Sawtooth is recorded against all the insects logged in Doi Inthanon National Park (12 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.
