The rosy grizzled skipper (Pyrgus onopordi) is a species of skipper (family Hesperiidae). This species can be found in central and southern Europe (Austria, Croatia, France, Germany, Italy, Portugal, Slovenia, Spain, Switzerland, and Netherlands) and in North Africa (Algeria and Morocco).
These butterflies inhabit flowery meadows, hot dry grassy meadows and streams at an elevation of 0–2,000 metres (0–6,562 ft) above sea level. The wingspan of Pyrgus onopordi can reach 22–28 mm. The upper side of the frontwings and hindwings is dark brown or khaki with a slight yellowish tinge, white markings, and a white fringe on the edge. The underside hindwings is light yellow-brown marbled with a few large white spots, including a characteristic anvil-shaped discal mark bordered with dark lines in the cells four and five. Females are darker and usually larger than males. Unlike most European Pyrgus species this skipper can usually be readily identified in the field as it is noticeably paler than its congeners. This is due to a heavy dusting of yellowish scales which overlies the dark brown base colour.
The eggs are yellowish, roundish, and flattened... Wikipedia →

With luck
About 10% of wildlife watchers report a Rosy Grizzled Skipper sighting in Sierra Nevada National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 390th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Rosy Grizzled Skipper in Sierra Nevada National Park on a given day, against under 5% in September to May, the lowest months. That is one of Sierra Nevada National Park's driest months, with about 30 mm of rain against 130 mm in March.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Rosy Grizzled Skipper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Rosy Grizzled Skipper sightings, Sierra Nevada National Park has the highest daily chance: about 10%. Next come Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Rosy Grizzled Skipper is recorded against all the insects logged in Sierra Nevada National Park (5 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.
