Tree Grayling; Sátiro moreno

The Tree Grayling (Hipparchia statilinus) is a butterfly of the family Nymphalidae. The underside is quite variable, especially the hindwing discal line, which is much stronger in the male which has a lighter post-discal band, giving a greater contrast, and the female often has a very faint discal line, sometimes almost non-existent. H. statilinus often flies in company with the False Grayling (Arethusana arethusa). It really is a mis-named butterfly as it has very little connection with trees, usually settling in hot weather on roads or low ground, often stones and rocks, but usually in positions which make getting photos difficult. The wingspan is 21–25 millimetres (0.83–0.98 in). The butterflies fly in one generation from June to October. The larvae feed on Corynephorus canescens, Bromus and other grasses.
