Elymnias hypermnestra, the common palmfly, is a species of satyrine butterfly found in South and Southeast Asia. As in some other species in the genus Elymnias, the common palmfly has a precostal cell in the hindwings and a tuft of androconial scales on the dorsal discal cell of the hindwings. Some populations of this butterfly species are sexually dimorphic: males and females do not look alike. In sexually dimorphic populations, males have black upperside forewings with small blue patches and mimic Euploea species, while the females mimic butterfly species of the genus Danaus.
Race undularis (Subhimalayas and Southeast Asia) male upperside blackish brown. Forewing with a subterminal series of blue or sometimes slightly green elongate spots, curving strongly inwards and getting more elongate opposite the apex, forming almost an oblique bar up to the costa. Hindwing: the terminal margin broadly bright chestnut, sometimes with a subterminal paler spot in two or more of the interspaces. Underside pale brown, the basal two-thirds of both forewing and hindwing densely, the outer third more sparsely covered with dark ferruginous, somewhat broad, transverse striae. Forewing...

Possible
About 20% of wildlife watchers report a Common Palmfly sighting in Hong Kong on a given day, based on 229 verified sightings from GBIF citizen-science data. It is the 42nd most-seen of the 1125 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.
March, June–September and November
In those months about 20% of wildlife watchers report a Common Palmfly in Hong Kong on a given day, against about 10% in April–May, October and December–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Common Palmfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
28th of 37
Of the 37 cities where we can rate Common Palmfly sightings, Hong Kong ranks 28th at about 20%. The best odds are in Hanoi (Vietnam, about 40%), Xiuying District (China, about 40%) and Jabalpur (India, about 30%).
Same family: Nymphalidae
The closest relatives of the Common Palmfly that you can see in Hong Kong (family Nymphalidae, Brush-footed Butterflies) are Ceylon Blue Glassy Tiger (about 30%), Blue-Spotted Crow Butterfly (about 30%) and Great Eggfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Palmfly is recorded against all the insects logged in Hong Kong (229 verified sightings), 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.
