Terinos terpander
In 3 days ~60% in a week ~90%
Terinos terpander, the royal Assyrian, is a butterfly in the family Nymphalidae. It was described by William Chapman Hewitson in 1862. It is found in the Indomalayan realm. It is the smallest species of the genus; at the same time it displays on the forewings the least-developed scent-patches; they not only begin beyond the cell, but do not flow together anteriorly, being represented along the upper radial by an isolated streak of thinly scattered scales. The hindwings are either orange-coloured in the distal half, or spotted with white in the anal area or they may be uniform blue, according to the locality. The under surface is red-brown, differing from all the other known species in being
adorned with very broad longitudinal fasciae of a vivid metallic gray lustre, which in some forms are accompanied on the hindwings by pure white submarginal bands. Wikipedia →

Possible
About 30% of wildlife watchers report a Royal Assyrian sighting in Khao Luang National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 36 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.
September

Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Royal Assyrian 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 Royal Assyrian is recorded against all the insects logged in Khao Luang National Park (10 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.
