Lopinga achine

— Larva green, with yellowish brown head.3 dark dorsal hues and pale double lateral stripe ; till May on Lolium, Poa, Triticum, etc.

The butterflies occur in woods of tall leaved trees, especially if there is a luxurious undergrowth, in June and July, the flight being dancing.

They pitch on bushes, drink on damp places of the roads and imbibe the sap of wounded trees.

Widely distributed in Europe, but sporadic and usually not very plentiful, being on the contrary extremely common in East Asia, assembling sometimes in swarms.

The woodland brown may be found in warm openings of damp unmanaged mature forests.
