Coordinator notes: This is actually Papilio multicaudata (Two-tailed Swallowtail), our commonest tiger swallowtail in cities along the Front Range. Papilio glaucus lacks the second tail on the hindwing, and is almost never found as far west as the Front Range, though it may sometimes be found in towns near Colorado’s eastern border. Thanks for submitting your sighting!
