The black swallowtail, Papilio polyxenes, is a large native CO butterfly with distinctive adult and larval (caterpillar) forms. The adults are striking butterflies with yellow spots lining the wings and blue spots and a “tail” on on the hind wing. Females can be distinguished by their more pronounced blue scales and smaller yellow spots.
