Black swallowtail (2nd instar larva)

Adult: a common member of the "blue-and-black" swallowtail complex. Female, with its large blue patches on hindwings, is a mimic of the Pipevine Swallowtail. Some female Black Swallowtails have little yellow on wings above. Males have more extensive broken yellow band. Note orange and black spot on inner margin of hindwings (Palamedes Swallowtail is otherwise very similar, above, but has no black center in the orange spot). (information from BugGuide)
