Pyrgus sidae (Esper, [1784]) in Toscana

Reports published between 1869 and 2023 and unpublished records collected between 1971 and 2023 suggest that Pyrgus sidae (Esper, [1784]) is a rare species with a restricted distribution in Tuscany. Indeed, it is only known from about twenty sites in 17 10x10 UTM squares which are reduced to 9 if only those covered with reports relating to the period 2000-2023. It lives from 70 m of 1029 m and flies between the first half of May and the first half of July. It frequents pastures and permanent meadows and above all xeric prairies, habitats of community interest and priority pursuant to Directive 92/43/EEC. To know the actual distribution of this species in Tuscany it is necessary to sample more accurately the central north of the region and confirm its presence in the localities where it was ascertained before 2000, in particular in those where it was collected between the second half of 1800 and the first half of the 1900s.
