Possible
About 30% of wildlife watchers report a Spotted Sawtooth sighting in Royal Manas National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 27 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.
April and May
In those months about 40% of wildlife watchers report a Spotted Sawtooth in Royal Manas National Park on a given day, against under 5% in March, the lowest month. July to October have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Spotted Sawtooth is recorded against all the insects logged in Royal Manas National Park (11 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.
