Dophla evelina, the red-spot duke, is a species of brush-footed butterfly found in Cambodia and across South and Southeast Asia, ranging from Sri Lanka, Yunnan, and India to the Philippines and Sulawesi. Many subspecies are recognised. The species was first described by Caspar Stoll in 1790.
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 Cuc Phuong National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 126 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 60% of wildlife watchers report a Redspot Duke in Cuc Phuong National Park on a given day, against under 5% in July to May, 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.
Yes
Of the 2 parks where we can rate Redspot Duke sightings, Cuc Phuong National Park has the highest daily chance: about 20%. Next come Sinharaja Forest Reserve (Sri Lanka, about 20%).
GBIF citizen-science records
It is estimated from how often the Redspot Duke is recorded against all the insects logged in Cuc Phuong 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.
