A research was conducted on the butterfly communities of 44 observation spots in the Sila Greca Massif. A quantitative collecting method was used that allowed to study both communities and fauna. Data were gathered from areas with known width. It has been possible to identify some typical communities and separate open lands from woodlands in each vegetation belt (biome of sclerophylls, samnitic belt and subatlantic belt). In the fauna of Sila Highland reside some populations of typically Mediterranean species because of its continental climate that increase summer temperatures. 94 species and 2401 specimens were found. Particularly interesting is the occurrence of Melitaea aetherie (Hubner, 1826) which was found only here in continental Italy. Furthermore, continental distribution of Sloperia proto (Ochsenheimer, 1808), Polyommatus daphnis ((Denis & Schiffermuller), 1775) and Hipparchia hermione (Linnaeus, 1764) has been southward enlarged. Chorological analysis shows that species occurring in Sila Greca which are spread over Europe are fewer than in Appennino Lucchese (Marini & Trentini, 1986); this is true even at high altitudes. Southward, it seems not existing the peninsula effect in butterfly fauna; in fact, Sila Greca have a butterfly diversity higher, or at least similar, than Appennino Lucchese.
