Lexias canescens has a wingspan of about 10 cm (3.9 in). These butterflies have dark brown and whitish or yellow-spotted upper surface of the wings, which is an efficient camouflage against predators. Caterpillars are pale green with long spinous bristles.
The male of Lexias canescens pardalina is rather similar to a small female of Lexias pardalis but the underside of its hindwings shows a yellow-washed color. Seitz-It is a small, insignificant species, differing from Lexias dirtea in having both sexes almost alike, but still resembling it in the red-brown palpi and the close resemblance of both sexes to the pattern of the female of E. dirtea F. The arrangement of the yellow spotting which varies on the different islands in which it occurs canascens canescens Btlr. (127 a) has the macular rows on the hindwings not always red-brown but usually pale clay-yellow. In the female the spots are larger, those in the median area of the forewing changing to white; moreover, the submarginal macular row of both wings is... Wikipedia →

With luck
About 10% of wildlife watchers report a Yellow Archduke sighting in Taman Negara National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 64th most-seen of the 84 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Yellow Archduke in Taman Negara National Park on a given day, against under 5% in March–April, June, August–October and December–January, the lowest months. That is one of Taman Negara National Park's wettest months, with about 330 mm of rain against 100 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow Archduke sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Yellow Archduke sightings, Taman Negara National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Danum Valley Conservation Area (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Archduke is recorded against all the insects logged in Taman Negara National Park (5 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.
