A small dark butterfly. The upperside is dark brown with purplish-blue suffusion. The underside is a pale greyish-brown, with a thin white “hairstreak” postdiscal line. The hindwing underside has an two orange spots near the anal angle with a tiny tail. Male and female are similar, with the female being more purple on the upperside. The butterfly could be confused with members of the genius Satyrium, especially S. ilicis which inhabits a similar habitat, but the lack of purple sheen and presence of a more obvious short tail on the hindwing enables separation.
Whilst the Ilex Hairstreak is commonly associated with the lower growing Oaks on the island, the Purple Hairstreak is more frequently seen on large Oak scrub and/or trees. It is a truly arboreal species, often seen in the canopy or roosting in the heat of the day in branches of the larger Oak scrub species. Consequently, its more often found in the wooded and scubby areas.
Meadow Vetchling Lathyrus pratensis - not on Corfu, Turkey Oak Quercus cerris, Kermes Oak Quercus coccifera, Hungarian Oak Quercus frainetto, Holm Oak Quercus ilex, Mount Tabor Oak Quercus ithaburensis, Downy Oak Quercus pubescens, Pedunculate Oak Quercus robur.
Almost certainly an under recorded species because it leads such a secretive life in the canopies of the various Oak species. It has been most commonly recorded by CBC members in the north east of the island.
