Tree Grayling

Hipparchia statilinus (Hufnagel, 1766)

Status

Description

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. 

Habitat Requirements

Mostly found on rocky mountainous habitat in the north east of Corfu.

Larval Foodplants

Barren Brome Anisantha sterilis, Annual Meadow Grass Poa annua, Stipa capensis, Stipa pulcherrima.

Observations

In Greece permits are required to net butterflies and so if you do not have such a permit different identification techniques need 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.
