Male upperside dark metallic green. Forewing: the cell has two median sinuous short black transverse lines with a crimson spot between them, and two similar lines beyond, one before and one after apex of cell; these are followed by a dark irregular transverse shading between the veins. The apex of the wing is broadly and termen narrowly edged with an obscure dark shading. Hindwing with a slender black loop in the cell; very obscure discal and subterminal dark macular bands; and the anterior third of the wing purplish.
The underside is sap green, largely suffused with plumbeous grey. The forewing has the transverse slender black lines and a crimson spot as on the upperside, along with a very obscure subterminal series of dark spots parallel to terminal margin. The hindwing has three crimson spots encircled by slender black loops near the base, and a very obscure subterminal series... Wikipedia →

Possible
About 20% of wildlife watchers report a Redspot Duke sighting in Sinharaja Forest Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 117 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Redspot Duke in Sinharaja Forest Reserve on a given day, against under 5% in March, May–June, October and December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Redspot Duke sightings with a recorded time, and about 9 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 Redspot Duke sightings, Sinharaja Forest Reserve ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Cuc Phuong National Park (Vietnam, about 20%).

GBIF citizen-science records
It is estimated from how often the Redspot Duke is recorded against all the insects logged in Sinharaja Forest Reserve (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.
