With luck
About 10% of wildlife watchers report a Boisduval's Hawkmoth sighting in Khao Yai National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 115th 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.
May and July–August
In those months about 20% of wildlife watchers report a Boisduval's Hawkmoth in Khao Yai National Park on a given day, against under 5% in April, June and September–February, the lowest months. Those are among Khao Yai National Park's wettest months, with about 240 mm of rain a month against 15 mm in December.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Boisduval's Hawkmoth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Khao Yai National Park, in our data
Khao Yai National Park is the only park on Wallace's Line with enough records to rate Boisduval's Hawkmoth sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Boisduval's Hawkmoth is recorded against all the insects logged in Khao Yai National Park (9 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.
