As with other Pyrgus species, this is very difficult to identify in the field. It is often paler than most of its congeners with a yellowish suffusion, especially in the female. The hindwings usually have pale markings forming a continuous band. The wingspan is 26–30 mm.See Juan L. Hernández-Roldán and Miguel L. Munguira 2008 for differentiation from P. alveus[1]

The adults are on the wing in July and August.

The larval food plant is Potentilla.

The species name honours Gedeon Foulquier.
