Eastern Rock Grayling

Hipparchia syriaca (Staudinger, 1871)

Status

Description

A dark brown medium sized butterfly with a broad white postdiscal band. It normally rests with its wings closed, with the cryptically coloured underside blending well within the background.. Males and females are similar. It could be easily confused with H. fagi or Brintesia circe. Males can only be separated fromH. fagi by examination of the Jullien by an expert, which at present has not been confirmed in Corfu. Separation from the larger Brintesia circe, which has a broken white postdiscal band on the forewing, along with two white marks along the costa of the underside. The hindwing underside has a prominent white postdiscal band, rather than a rather cryptic underside, and white discal band.

Habitat Requirements

A tree hugging butterfly that can frequently be seen doing just this in Old Perithia. 

Larval Foodplants

Yorkshire-fog Holcus lanatus

Observations

The Eastern Rock Grayling's behaviour and appearance is so similar to that of the Woodland Grayling Hipparchia fagi, that the occurance of the Eastern Rock Grayling might be masking the existance of this other species. Genetalia examination or DNA analysis are the only true ways ahead.
