Foulquier's grizzled skipper

Foulquier's grizzled skipper, Pyrgus bellieri, is a small butterfly of the skipper family Hesperiidae, also listed under the synonym P. foulquieri. Its range is limited to central and southern France and adjacent areas of Spain and Italy, and it also occurs on Corsica. Within that range it can be quite common. Like other Pyrgus skippers it is very difficult to identify in the field. It is often paler than most of its relatives, with a yellowish suffusion that is strongest in the female, and the hindwings usually carry pale markings that form a continuous band. The wingspan is 26 to 30 mm. Adults fly in July and August, and the larval food plant is a cinquefoil of the genus Potentilla. The species name honours Gedeon Foulquier. Separating it from the similar P. alveus is covered in a 2008 identification paper by Hernandez-Roldan and Munguira.
