PAPILIO ULYSSES & PAPILIO LORQUINIANUS ALBERTSI set |
The Ulysses butterfly (Papilio ulysses), also known as
the blue mountain butterfly, or the blue mountain swallowtail is a large
Australian swallowtail. The Ulysses butterfly has a wingspan of about 14 cm (5.5
inches). It lives in northeastern Australia along the coast of Queensland. It
inhabits tropical rainforest areas and suburban gardens. The Ulysses butterfly's
favorite food plant is euodia (Melicope elleryana), a tree with clusters of
small pink flowers growing straight out of the branches. The upper side the
wings are an iridescent electric blue; the underside is a more subdued black and
brown in coloration. The colors are produced by the microscopic structure of the
scales.[1]
The female of the species differs from the male in that she has little crescents
of blue in the black sections of her hind wings. When the butterfly is perched
the intense blue of its wings is hidden, helping it to blend in with its
surroundings. When in flight the butterfly can be seen hundreds of meters away
as sudden bright blue flashes. This butterfly is used as an emblem for
Queensland tourism.
