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 Mercantour National Park on a given day, based on 52 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 412 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 Mercantour National Park on a given day, against under 5% in January–May and September–November, 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.
Yes
Of the 4 parks where we can rate Titania's Fritillary sightings, Mercantour National Park has the highest daily chance: about 30%. Next come Vanoise National Park (France, about 30%) and Ecrins National Park (France, about 10%).

GBIF citizen-science records
It is estimated from how often the Titania's Fritillary is recorded against all the insects logged in Mercantour National Park (52 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.
