Lopinga deidamia

The wingspan is 45–55 mm. Seitz describes it thus-P. deidamia Ev. (menetriesi Brem.) (45 f). The male above somewhat similar to the menara male, the female with white spots proximally to as well as below the apical ocellus: both sexes recognizable by the underside, which is dark blackish brown and without the dentate hues found in the megera- maera -groups of forms. Very widely distributed, from the Ural throughout Asia, Siberia, Tibet. China and Japan. — In Korea occurs the dark form erebina Btlr., which is characterized by the more pointed forewing and strongly enlarged apical ocellus. — More singly, in some countries restricted to mountainous districts, the insect flying under trees and on road-sides, settling at puddles, the flight being weak and lazy. In the south of its area in May and again from August onward , in certain districts of China and in Amurland in July:usually rare. As in the case of maera a whole series of special forms might be separated in accordance with locality and season.[2]

Adults are on wing from June to August in one or two generations per year.[3]

The larvae feed on Agrostis, Calamagrostis and Elytrigia species.[4]
