With luck
About 10% of wildlife watchers report an Amerila astreus sighting in Khao Yai National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 149th most-seen of the 221 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report an Amerila astreus in Khao Yai National Park on a given day, against under 5% in July and October–May, the lowest months. That is one of Khao Yai National Park's wettest months, with about 260 mm of rain against 15 mm in December.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Amerila astreus sightings with a recorded time, and about 8 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 Amerila astreus sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Amerila astreus that you can see in Khao Yai National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Lymantria bivittata (about 20%), Cyana bellissima (about 10%) and Yellow Underwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Amerila astreus is recorded against all the insects logged in Khao Yai 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.
