The Twin-spotted Sphinx (''Smerinthus jamaicensis'') is a moth of the Sphingidae family. It is widely distributed across North America and is found everywhere except in the southern half of western California. It has been taken as far north as the Yukon. It has a wingspan of 1–3 inches (4.5–8.3 cm), with the outer margins of the forewings unevenly scalloped, but with the coastal margin of hindwings being almost straight. Males have gray with black and white markings on their forewings, while females are yellowish brown with dark brown and white markings. Both sexes have red hindwings with a pale yellow border. Sometimes a blue patch may appear as a single eyespot or it may be divided by black bands, creating two or three eyespots. Adult moths are nocturnal, but seem to prefer the earlier part hours of the night. The larvae feed on Apple (''Malus sylvestris''), ''Prunus'' species (such as plums and peach), Ash (''Fraxinus''), Elm (''Ulmus''), Poplar (''Populus''), Birch (''Betula'') and Willow (''Salix''). ==See also== *Smerinthus cerisyi *Smerinthus saliceti 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「Smerinthus jamaicensis」の詳細全文を読む スポンサード リンク
