Twenty five years of research (1994-2019) on the rhopaloceran fauna of the Monte Amiata, integrated with bibliographical sources, showed 89 species. The most numerous species are those that live in the forests, those linked to the edges of the woods and those that prefer high-hill and mountain areas. The most significant species for conservation value, biogeographical interest and because they are not so frequent elsewhere in Tuscany and in Italy, are Hamearis lucina (Linnaeus, 1758), Satyrium w-album (Knoch, 1782), Cupido argiades (Pallas, 1771), Argynnis pandora ([Denis &
Schiffermüller], 1775) and Brenthis hecate ([Denis & Schiffermüller], 1775)
