The adult is a small fritillary with a typically chequered orange-brown upperside and a marginal row of triangles and dots. The length of the forewings is 21–23 mm.
The underside has brown pearly spots and triangular markings at the edge of the hindwings. A. amathusia Esp. (= diana Hbn., titania Esp., dia major Esp.) (68e). Above similar to large specimens of euphrosyne. The hindwing beneath is very characteristic, being strongly variegated with purple, its distal band deeply dentate on both sides and bearing purple-brown partly pale-centred dots. In the nymotypical form the forewing beneath also shows at the distal margin pointed teeth which project far on to the disc... In the Alps. — bivina Fruhst. is the eastern European form; smaller, paler, with somewhat thinner lilac markings; darker beneath, the median band of the hindwing more uniformly yellow, not being variegated with red; from Saratow. — In sibirica Stgr.[B. titania ssp. staudingeri Wnukowsky, 1929] (68f) the band occupying the distal...

Possible
About 30% of wildlife watchers report a Titania's Fritillary sighting in Vanoise National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 308 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Titania's Fritillary in Vanoise National Park on a given day, against under 5% in September–October and December–May, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Titania's Fritillary sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Titania's Fritillary sightings, Vanoise National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Mercantour National Park (France, about 30%).
GBIF citizen-science records
It is estimated from how often the Titania's Fritillary is recorded against all the insects logged in Vanoise National Park (38 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.
