Agriades pyrenaicus, the Gavarnie blue, is a Palearctic butterfly of the family Lycaenidae. It is found in the Asturias Mountains of north-western Spain, the Pyrenees, the southern Balkan Peninsula, Turkey, the Caucasus and Armenia. The habitat consists of alpine grassy rocky meadows where it is found at altitudes ranging from 1,500 to 2,200 meters.
The wingspan is 22–28 mm. The wings are grey suffused with blue and the wings are bordered by a white line. On the upperside a grey discal spot centers each wing, on the underside the forewings are decorated with black dots circled in white and the hindwings have a sub-marginal line of white dots some centered yellow.
The larvae feed on Androsace species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Gavarnie Blue sighting in Pyrénées National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1144th 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 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Gavarnie Blue in Pyrénées National Park on a given day, against under 5% in August to June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Gavarnie Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Gavarnie Blue sightings, Pyrénées National Park ranks 2nd at under 5%. The best odds are in Picos de Europa National Park (Spain, about 20%).
GBIF citizen-science records
It is estimated from how often the Gavarnie Blue is recorded against all the insects logged in Pyrénées National Park (8 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.
