A dark brown medium sized butterfly, which normally rests with its wings closed, with the cryptically coloured underside blending well within the background. There is a large black spot, yellow ringed, usually with a white pupil on the forewing underside. The key diagnostic feature are two postdiscal white spots in the centre of the forewing which are usually present, visible on both side. A very variable butterfly which can be confused with H. fatua, which has well defined basal, discal and submarginal wavy lines on the hindwing underside, and usually without the two white spots in the forewing.
Rocky habitats, particularily easy to locate on the limestone pavement beneath Mt Pantokrator.
Barren Brome Anisantha sterilis, Annual Meadow Grass Poa annua, Stipa capensis, Stipa pulcherrima.
In Greece permits are required to net butterflies and so different identification techniques can be used to determine the species. Slow motion video photography, can be taken with a smart phone, to reveal the normally closed upperwings of the Tree Grayling, exposing the diagnostic double white spots on the forewings.
