Parantica aglea, commonly known as the glassy tiger, is a butterfly found in the Indomalayan realm. The species is a member of the Danainae subfamily of the Nymphalidae family. Several subspecies are recognized. In the British Museum's collection, there are specimens of the true Parantica aglea aglea from Myanmar, as well as others, indistinguishable from the typical Parantica aglea melanoides, from Mysore.
The ground color of this species is a sooty black, with subhyaline bluish-white streaks and spots. On the forewing, the 11th vein is fused with the 12th. Additionally, the first interspace of the upperside forewing has two relatively long, broad streaks that unite at the base and are truncated outwardly. The cell contains a very broad, somewhat club-shaped streak, traversed by two fine black lines. Interspaces 2 and 3 display basal spots, an irregular discal series of three spots and two elongated streaks, as well as a subterminal series of spots. These two series curve inward opposite the apex of the wing, with the latter continuing along the apical half of the costa. Finally, a terminal row of smaller paired spots appears... Wikipedia →

Possible
About 30% of wildlife watchers report a Glassy Tiger sighting in Royal Manas National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 27 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 60% of wildlife watchers report a Glassy Tiger in Royal Manas National Park on a given day, against under 5% in March, the lowest month. That is one of Royal Manas National Park's wettest months, with about 770 mm of rain against 10 mm in December. July to October have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Glassy Tiger 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 10
Of the 10 parks where we can rate Glassy Tiger sightings, Royal Manas National Park ranks 2nd at about 30%. The best odds are in Cuc Phuong National Park (Vietnam, about 40%).
Same family: Nymphalidae
The closest relatives of the Glassy Tiger that you can see in Royal Manas National Park (family Nymphalidae, Brush-footed Butterflies) are Chocolate Pansy (about 40%), Common Mapwing (about 40%) and Striped Blue Crow (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Glassy Tiger is recorded against all the insects logged in Royal Manas National Park (8 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.
