The Canadian tiger swallowtail (''Papilio canadensis'') is a species of the family Papilionidae. It was once classified as a subspecies of ''Papilio glaucus''. ==Description== ;Adult The wingspan of this particular species is 67 to 80 mm. The two adult morphs are yellow and black, although the black form is considered quite rare. This species is very similar to the eastern tiger swallowtail, but has a noticeably smaller wingspan. Unlike it, the underside, yellow marginal band is continuous. The hind wing has many orange scales, on both morphs. This species has also been known to hybridize with both the eastern and western tiger swallowtail, though extremely rarely. ;Caterpillar The caterpillar is large and green, with an enlarged head. It has four yellow dots and two false eyes with bluish centers. In profile, this caterpillar appears snake-like. The immature larvae are brown and white to mimic bird droppings, making them unappealing to predators. 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「Papilio canadensis」の詳細全文を読む スポンサード リンク
