Distribution. Korea, Japan.

Host plants. Cornaceae . Cornus kousa F. Buerger ex Hance ( Oku, 1974; Togashi, 1982); Swida macrophylla (Wall.) Soják ( Oku, 2003) .

Remarks. This species occurs in southern provinces of Korea. Hedya corni is similar to Hedya inornata (Walsingham) but differs from the latter in having the reddish brown forewings (dark brown in H. inornata ). Oku (2003) stated that the larvae of H. corni tie two leaves of host plants and feed inside tissues. Later they cut circularly one of the leaves and fold to make a pupal chamber.
