The Ulysses Butterfly (Papilio ulysses) is a large Australian swallowtail with a wingspan of about 14 cm (5.5 in). The top of the butterfly’s wings are an iridescent electric blue; the underside is a more subdued black and brown coloration. When the butterfly is perched the intense blue of its wings is hidden (as seen here), helping it to blend in with its surroundings.
