Papilio troilus
Spicebush Swallowtail, Green-clouded Butterfly
Papilio troilus, the spicebush swallowtail, is a black swallowtail butterfly native to eastern North America. Adults are primarily black with distinctive green-blue (male) or bright blue (female) half-moon markings on the hindwings, along with cream-yellow spots and orange basal patches. The species exhibits two subspecies: the widespread P. t. troilus and the Florida-endemic P. t. ilioneus. Larvae are notable for their dramatic ontogenetic color change, shifting from bird-dropping mimicry in early instars to snake-mimicry with large eyespots in later stages.
