Likely
About 40% of wildlife watchers report a Spotted Sawtooth sighting in Namdapha National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 71 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report a Spotted Sawtooth in Namdapha National Park on a given day, against about 10% in February and March, the lowest months. That is one of Namdapha National Park's driest months, with about 20 mm of rain against 660 mm in July. June to August have too few records to rate.
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.

GBIF citizen-science records
It is estimated from how often the Spotted Sawtooth is recorded against all the insects logged in Namdapha National Park (14 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.
