''Rhagastis castor'' is a moth of the Sphingidae family. It is known from Nepal, north-eastern India, Thailand, southern China and Vietnam, Sumatra, Java and Taiwan. The wingspan is 53–84 mm. It is similar to ''Rhagastis acuta'' and ''Rhagastis velata'' but larger, the forewings and hindwings are more elongate. It is distinguishable by the combination of the dark connection between the marginal band and the basal area on the forewing underside and the well developed abdominal golden stripes. The forewing underside marginal area is joined to the basal area by a streak. The third postmedian line is marked by a series of large and conspicuous black vein dots. The fore- and hindwing median area has a conspicuous red or salmon pink flush. Larvae of ssp. ''aurifera'' have been recorded feeding on ''Amorphophallus'' and ''Vitis'' species in India. The larvae of ssp. ''formosana'' feed on ''Saurauia'' species. ==Subspecies== *''Rhagastis castor castor'' (Sumatra and Java) *''Rhagastis castor aurifera'' (Butler, 1875) (Nepal, north-eastern India, Thailand, southern China and Vietnam) *''Rhagastis castor formosana'' Clark, 1925 (Taiwan) *''Rhagastis castor jordani'' Oberthür, 1904 (southern China) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rhagastis castor」の詳細全文を読む スポンサード リンク
