About Coenonympha corinna Hübner, 1803
This entry covers Coenonympha corinna Hübner, 1803, also known as norax Bon. It is the smallest species in the Coenonympha genus. The upperside of its wings is a bright yellowish red, with a broad black marking on the apex of all wings. On the forewing, this black colour extends inward as a submarginal stripe, reaching all the way to the inner angle. On the underside, the forewing is uniformly yellowish red and has a small apical ocellus. The hindwing has a darker basal area, and small ocelli with highly variable development are present in its lighter-coloured marginal region. The subspecies elbana Stgr., found on the island of Elba, has an apical ocellus on the wing upperside that lacks a central pupil, and the ocelli on the underside of its hindwing are larger than those of the nominal subspecies. Coenonympha corinna can be found in Sardinia, Corsica and Sicily, where it is locally very abundant. It flies in two broods: one in May and June, and a second starting in July. The larva is light green, with a dark dorsal line bordered by pale edges, and a yellowish side-line shaded with dark colour. Its recorded host plants are Carex gynomane and Triticum cespitosum; it feeds on grasses in general. The pupa is reddish grey, with white smears and markings.
