O. carnipennis was describ efdrom Yokohama, Japan ,and is known to inhabit China
(HeilongjPiraovn.)(Chen,1982),USSR (thePrimoryterritory)<Kononenke1,990),Taiwan
(Sug i19,86) and Japan (Hokkaido H,onshu, Shikoku, Kyushu). Its larvae were repeatedly
illustrate din Japan (Kawada ,1950 ; Yamamoto, Y., 1965 ; Ujiie ,1972 ; Yamamoto, M,,
1987) ,and descriptio nwsere given by Yamamoto, Y, (196 5a)nd Ujii e{1972 )L,arva feeds
on various kinds of broad-leaved deciduou strees ,making a nest by folding a leaf of host
plant medially.
