Località di raccolta inedite di Satyrium w-album (Knoch, 1782) in Toscana

The new records relate to twenty-two localities, eight of which are in the province of Siena, four in the province of Grosseto, three of Arezzo and Florence, two of Massa Carrara, one of Livorno and one of Pisa. The localities are located inside or at the edge of wooded areas, from a minimum of 45 m to a maximum of 915 m above sea level. The flight period is between the second fortnight of May and the first fortnight of August, with a maximum of observations in June (59,1% of cases). Since it is an uncommon species that lives in habitat in progressive alteration by humans, S. w-album is believed to be threatened in Tuscany.
