A small butterfly common in southern Europe, North Africa, and the Middle East. In Israel it can be found in the eastern mountain region (from the Judean Hills, Samaria, to the Golan Heights and Mount Hermon). It flies in spring during April and May. Its wingspan is about 25 mm. It has one generation a year.
The female lays her eggs on the leaves of Bulbous barley and other perennial cereals. The egg is cream-colored and oval-shaped.
The larva hatching from the egg is yellowish and has a black head. After hatching, it enters diapause until the following spring. For protection, it lives inside a folded leaf that it makes. As it grows, its color turns green with light stripes לאורך it. When it reaches a size of about 25 mm, it pupates, usually on the leaf.
The pupa is of the girdled pupa type. It is light green and has cream-colored longitudinal stripes. Its length is about 20 mm. At the front of the pupa there is a pointed protrusion. Its duration is about two to three weeks.

Former name: the barley skipper
