Archigenes neophron, the tailed Judy, is a small butterfly found in India that belongs to the Punches and Judies family (Riodinidae). They were formerly placed in the genus Abisara but have since been moved to a separate group based on phylogenetic studies.
Termen of hindwing has a long tail at apex of vein 4, the portion above it prominently emarginate. Upperside is brown varying in tint, but generally paler in the female than in the male. Forewing with a comparatively broad oblique white band from middle of costa to near apex of vein 1 above the tornal angle, narrowed posteriorly; beyond this an ill-defined narrow, somewhat more erect, pale dusky-white band from costa to dorsal margin, curving slightly round the tornal termination of the inner broader band; an inner and an outer slender abbreviated subterminal line extending in the female from vein 1 to vein 4, shorter in the male. Hindwing has a postdiscal sinuous, ill-defined, broad transverse band, paler than the ground colour, bordered on the inner and outer sides by very obscure lunular dull whitish lines, followed by two slender pure white subterminal broken lines that in interspaces 4 and 5 are bordered inwardly...

With luck
About 10% of wildlife watchers report a Tailed Judy sighting in Khao Yai National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 149th most-seen of the 221 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Tailed Judy in Khao Yai National Park on a given day, against under 5% in May to November, the lowest months. That is one of Khao Yai National Park's driest months, with about 20 mm of rain against 330 mm in September.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Tailed Judy sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Tailed Judy sightings, Khao Yai National Park ranks 2nd at about 10%. The best odds are in Doi Inthanon National Park (Thailand, about 20%).
Same order: Lepidoptera
The closest relatives of the Tailed Judy that you can see in Khao Yai National Park (order Lepidoptera, Butterflies and Moths) are Magpie Crow Butterfly (about 40%), Paris Peacock Swallowtail (about 40%) and Common Bluebottle (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tailed Judy is recorded against all the insects logged in Khao Yai National Park (6 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.
