Oberthür's grizzled skipper (Pyrgus armoricanus) is a species of skipper (family Hesperiidae). Pyrgus armoricanus has a wingspan of 24–28 mm. Both wings have a white fringe along the edges. The upperside of the forewings is dark brown with well developed white markings. On the recto of the hindwings there are clearly visible grayish marks. The underside of the hindwings shows a pale reddish-brown colour with a large pale discal spot and light coloured veins. The males and females are similar in appearance.
Like all Pyrgus species, Pyrgus armoricanus can be very difficult to identify in the field. The upperside of the forewings are often noticeably darker brown than other Pyrgus species, especially when fresh, with clear white markings. It resembles some smaller races of large grizzled skipper (P. alveus). It is slightly larger than Pyrgus malvae. This species is also quite similar to Pyrgus carthami and Pyrgus serratulae. Without a genital examination, there is a high risk of confusion, especially with butterflies of the Pyrgus alveus complex and with Pyrgus cirsii. Compared to Pyrgus alveus, however, the white spots on the upper side of the hind wing are clearly... Wikipedia →

Rare
Under 5% of wildlife watchers report an Oberthür's Grizzled Skipper sighting in Pyrénées National Park on a given day, based on 5 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.
April and May
In those months about 10% of wildlife watchers report an Oberthür's Grizzled Skipper in Pyrénées National Park on a given day, against under 5% in June to March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Oberthür's Grizzled Skipper sightings with a recorded time, and nearly all 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 Oberthür's Grizzled Skipper sightings, Pyrénées National Park ranks 2nd at under 5%. The best odds are in Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Oberthür's Grizzled Skipper is recorded against all the insects logged in Pyrénées 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.
