Lamproptera meges, the green dragontail, is a species of swallowtail butterfly (family Papilionidae) found in parts of South Asia and Southeast Asia. There are ten subspecies. A specimen from Java is the type species of the genus Lamproptera.
A small butterfly, the green dragontail has a wingspan of 40 to 55 millimetres (1.6 to 2.2 in). It is basically black and white in colour scheme, it has a very large white-tipped tail, 25 to 40 millimetres (0.98 to 1.57 in) long. The forewing has a triangular hyaline (glass-like) patch with black borders, and thin black stripes along the veins, forming six to eight spot/bands. It also has a pale band running obliquely across the pre-discal area. This band is continued onto the black hindwing which bears the long tail and prominent abdominal wing fold. In this species, the pale bands are light green while in its closely related species, Lamproptera curius, they are white. Also in L. curius, the white band has a hyaline outer edge. Sexes are alike, but the female is duller and has a ventral copulation groove before the tip of the abdomen. The males of this species do not have the sex mark (scent organ) found in L. curius.

Likely
About 50% of wildlife watchers report a Green Dragontail Butterfly sighting in Cuc Phuong National Park on a given day, based on 85 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 126 insects we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 80% of wildlife watchers report a Green Dragontail Butterfly in Cuc Phuong National Park on a given day, against under 5% in January, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Green Dragontail Butterfly 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 7 parks where we can rate Green Dragontail Butterfly sightings, Cuc Phuong National Park has the highest daily chance: about 50%. Next come Cat Tien National Park (Vietnam, about 40%) and Kerinci Seblat National Park (Indonesia, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Green Dragontail Butterfly is recorded against all the insects logged in Cuc Phuong National Park (85 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.
