Further, most not so sharply defined stains are formed in the apical area of the postdiscal area. Occasionally, the subterminal line at least in the front half of the wing is indicated.

Therefore, some specimens seem very dark. Adults are on wing from the end of July to August in one generation. The larvae feed on
