Black Swallowtail (Papilio polyxenes)Observer
ansel_oommenDescription
Three native swallowtail larvae side by side for comparison. From left to right: Eastern tiger swallowtail (Papilio glaucus), Eastern black swallowtail (Papilio polyxenes) and spicebush swallowtail (Papilio troilus). Note snake mimicry of both Eastern tiger and spicebush swallowtail caterpillars. Note aposematic coloration of Eastern black swallowtail. The adults of these three species participate in a Batesian mimicry complex in which they mimic the highly distasteful pipevine swallowtail (Battus philenor)
