The Red Spotted Purple butterfly is a striking species with black wings overlaid by shimmering blue or blue-green scaling. When viewed in sunlight, the wings exhibit a brilliant iridescent blue sheen that seems to shift with movement. The undersides contrast sharply, featuring bold red-orange spots that give the butterfly its name. This species is a clever mimic of the toxic Pipevine Swallowtail, but unlike its model, the Red Spotted Purple lacks the characteristic tails on its hindwings.
