On my trips to the hills of Lefkada in late May and early June, I have always encountered two particular species of Hairstreak both nectaring together on roadside flowers and bramble flowers.Perhaps the most attractive of the two is the Blue-spot Hairstreak with its square shaped blue 'eye' at the base of the hind wing.In Greece and the surrounding areas it is a prolific butterfly whereas in the north of its range ie extending as far as northern France it is generally in decline.
The second species is the Ilex Hiarstreak,similar to its companion but without the blue spot.In contrast to the Blue-spot it can be widespread and common especially through south and central Europe.
