The genus Hipparchia Fabricius, 1807 in the province of Siena is represented by three species: Hipparchia fagi (Scopoli, 1763), Hipparchia semele (Linnaeus, 1758) e Hipparchia statilinus (Hufnagel, 1766). Hipparchia fagi is widespread; attends mostly woods, between a minimum of 150 m up to 895 m altitude, with flight time between the first fortnight of June and the first fortnight of October. Hipparchia semele is poorly distributed; attends mostly natural grasslands and
pastures, between a minimum of 290 m and a maximum of 1015 m above sea level, with flight time between the second fortnight of June and the second fortnight of September. Hipparchia statilinus is widespread; attends mostly woods and natural grasslands, between a minimum of 170 m and a maximum of 1148 m above sea level, with flight time between the second fortnight of June and the first fortnight of October. At present, no risk factors are known to threaten these species in the Siena district. For the protection of their populations it is suggested to keep the woods, the prairies and the
meadows-pastures
