The Alpine Grizzled Skipper (Pyrgus andromedae) is a species of skipper (family Hesperiidae). Description This is a medium-sized Pyrgus skipper with a wingspan of 26–30 mm. The dark brown forewing is marked with a bold pattern of white spots; by contrast the hindwing is plain dark brown with little or no patterning. The underside of the hindwing has two distinctive pale markings close to the dorsum: an elongated streak and a round spot, often likened to an exclamation mark (!). In cases of doubt, an examination of the genitals should be carried out for a reliable determination. Range The Alpine Grizzled Skipper is the only boreo-alpine Pyrgus species in Europe. It is found at high altitudes in Europe. This species is found up to fairly high altitudes in the Alps, Pyrenees (rare) and Pirin and also at lower elevations in northern Scandinavia, where its range extends well into the Arctic Circle. It is also known from the Carpathians, southwest Bosnia, southwest Serbia, northwest North Macedonia, Lapland and the border between Norway and Sweden. This is a European endemic species. Habitat In the Alps and Pyrenees, its natural habitat is above the tree line in damp, grassy places, often near streams or in bogs. In its Scandinavian range it occurs in areas with dwarf scrubby vegetation and on steep slopes and in rocky areas. It prefers damp habitats and is often found near to water. The main occurrences of P. andromedae are in the Alps in the Sesleria caerulea and Carex firma-dominated grasslands of calcareous locations at the alpine altitude. In low altitudes below 800 m, gravel banks in the alluvial areas of mountain rivers and their peripheral areas are usually occupied. Habitats in the subalpine level are light mountain forests interspersed with poor grass, stony and poor alpine pastures, avalanche lines, rubble heaps, brook banks, feistluras or embankments with pioneer lawns created by road construction. In the Swiss Alps its height range is and in the Pyrenees . In Bavaria the species can usually be found at an altitude range of 900 m to 2000 m. Ecology P. andromedae occurs in one generation per year throughout its range. The first imagos were observed in Bavaria from mid-May. The main flight time falls from the beginning of June to mid-July, from the first week of August there is only a very small amount of evidence. The phenology is strongly dependent on
