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 30% of wildlife watchers report a Common Palmfly sighting in Ho Chi Minh City on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 121 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.
January
In that month about 40% of wildlife watchers report a Common Palmfly in Ho Chi Minh City on a given day, against under 5% in May and August, the lowest months. That is one of Ho Chi Minh City's driest months, with about 10 mm of rain against 220 mm in October.
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.
14th of 37
Of the 37 cities where we can rate Common Palmfly sightings, Ho Chi Minh City ranks 14th at about 30%. 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 Ho Chi Minh City (family Nymphalidae, Brush-footed Butterflies) are Great Eggfly (about 40%), Leopard Lacewing Butterfly (about 40%) and Grey Pansy (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 Ho Chi Minh City (35 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.
