Melitaea didyma, the spotted fritillary or red-band fritillary, is a Palearctic butterfly of the family Nymphalidae. Melitaea didyma is a medium-sized butterfly with a wingspan reaching 35–50 millimetres (1.4–2.0 in). The overside of the wings is a bright orange-brown with dark brown markings arranged in rows, which are quite variable in quantity and size. Sometimes the colour of the females is a duller orange, shaded with grey-green. The underside of the wings is chequered pale yellow and pale orange.

On the underside, which is very abundantly marked with small black dots and hooks, a flexuose subbasal band and a curved submarginal one are situated on a delicately greenish, or yellowish, white ground. In the female the forewing and the anal area of the hindwing are much paler, being moreover dusted with blackish, while the costal half of the hindwing has preserved the... Wikipedia →

Possible
About 30% of wildlife watchers report a Spotted Fritillary sighting in Cévennes National Park on a given day, based on 172 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 996 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.
May and August
In those months about 40% of wildlife watchers report a Spotted Fritillary in Cévennes National Park on a given day, against under 5% in October to February, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spotted 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 9 parks where we can rate Spotted Fritillary sightings, Cévennes National Park ranks 4th at about 30%, level with the leaders once rounded. The best odds are in Vanoise National Park (France, about 30%), Aigüestortes National Park (Spain, about 30%) and Mercantour National Park (France, about 30%).

GBIF citizen-science records
It is estimated from how often the Spotted Fritillary is recorded against all the insects logged in Cévennes National Park (172 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.
