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...

Possible
About 20% of wildlife watchers report a Tailed Judy sighting in Doi Inthanon National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 153 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.
January and March
In those months about 30% of wildlife watchers report a Tailed Judy in Doi Inthanon National Park on a given day, against under 5% in June to November, the lowest months. Those are among Doi Inthanon National Park's driest months, with about 40 mm of rain a month against 340 mm in August.
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.
Yes
Of the 2 parks where we can rate Tailed Judy sightings, Doi Inthanon National Park has the highest daily chance: about 20%. Next come Khao Yai National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Tailed Judy is recorded against all the insects logged in Doi Inthanon National Park (17 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.
