Euphydryas desfontainii
In 3 days ~10% in a week ~30%
Euphydryas desfontainii, the Spanish fritillary, is a species of butterfly in the family Nymphalidae. It is found in France, Portugal, Spain, Morocco (the Rif mountains and Middle Atlas) and western Algeria in North Africa.
The wingspan is 40–45 mm. In desfontainii Godt. (= desfontainesi Bdv.), which was separated as a distinct species, because it occurs in the same districts as iberica, the proximal edge of the submarginal band of the forewing is very strongly flexuose, the distal margin bears small light rings or lunules placed in dark hastate spots; the submarginal band is almost so broad as in iberica and contrasts strongly with the light yellow discal band which stands at its proximal side and is broadly bordered with deep black. In baetica Rbr. from Andalusia, the submarginal band is so broad that it occupies the external third of the forewing and almost the outer half of the hindwing.
Adults are on wing from April to June in one generation per year. The larvae feed on Dipsacus, Scabiosa, Cephalaria and Knautia species (including Knautia arvensis). The species overwinters in the larval stage. Pupation takes place in spring.

With luck
About 10% of wildlife watchers report a Spanish Fritillary sighting in Pyrénées National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 576th 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.
May
In that month about 20% of wildlife watchers report a Spanish Fritillary in Pyrénées National Park on a given day, against under 5% in June to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Spanish Fritillary sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Spanish Fritillary sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spanish Fritillary is recorded against all the insects logged in Pyrénées National Park (27 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.
