Charaxes jasius, the two-tailed pasha, is a butterfly in the family Nymphalidae. It is the only European species of the genus Charaxes.

Charaxes jasius is a medium to large butterfly with a wingspan reaching 76–83 mm in males, the female being larger. Males up to 80–100 mm wingspan, with females even larger, may be found in Morocco. Each hindwing bears two tails, characteristic of most species of the genus. The spring seasonal brood is smaller in size compared with the second and sometimes third broods, and the two tails on each hindwing tend to curve somewhat towards each other resembling a pincer, less so in the later broods with slightly longer straighter tails. The upperside ground colour of the wings is dark brownish-black, with some changeable purplish sheen viewed at varying angles; forewing with suggestion of darker discal bars, postdiscal spots orange; hindwing with whitish patch near costal border, dusted with brownish scales; outer border of...

Rare
Under 5% of wildlife watchers report a Two-Tailed Pasha sighting in Pyrénées National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 738th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report a Two-Tailed Pasha in Pyrénées National Park on a given day, against under 5% in November to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Two-Tailed Pasha sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 9
Of the 9 parks where we can rate Two-Tailed Pasha sightings, Pyrénées National Park ranks 9th at under 5%. The best odds are in Waterberg Plateau Park (Namibia, about 40%), Gonarezhou National Park (Zimbabwe, about 30%) and Monfragüe National Park (Spain, about 30%).
Same family: Nymphalidae
The closest relatives of the Two-Tailed Pasha that you can see in Pyrénées National Park (family Nymphalidae, Brush-footed Butterflies) are Small Tortoiseshell (about 30%), Silver-Washed Fritillary (about 30%) and Speckled Wood (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Two-Tailed Pasha is recorded against all the insects logged in Pyrénées National Park (10 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.
