Troides magellanus, the Magellan birdwing, is a large and striking birdwing butterfly found in the Philippines and on Taiwan's Orchid Island.
This butterfly is named for the explorer Ferdinand Magellan who was killed in the Philippines in 1521.
Male: The forewings are ground colour black. The veins are bordered by white. The underside of the forewings is very similar to the upperside, but some veins are bordered by yellow. The hindwings are golden yellow. The veins and the marginal edge of the hindwing are black. The golden area has an opal, green or blue colour at a certain angle. The underside of the hindwing is very similar to the upperside and also has the optical effect.
The body (abdomen) is yellowish, but the underside is yellow. Head and thorax are black.
Female: is sexually dimorphic. The female is larger than the male. The ground colour of the female is dark brown to black. The veins are bordered by white colour shading. There is a golden area with dark veins on the hindwings. At the edge there is a postdiscal chain of golden spots. The underside is very similar to the upperside.
T. magellanus shows a blue-green sheen if viewed from an oblique angle. Troides magellanus and the much rarer T. prattorum , are noted for their use of limited-view iridescence: the yellow of the dorsal hindwings is modified by bright blue-green iridescence which is only seen when the butterfly is viewed at a narrow, oblique angle. This "grazing iridescence" is brought about through diffraction of light (after back reflection) by the wings' extremely steeply set, multilayered rib-like scales (rather than the ridge-lamellae of most other iridescent butterflies, such as Morpho species). Such limited-view iridescence was previously only known from one other species, the lycaenid Ancyluris meliboeus . In A. meliboeus, however, the iridescence is produced by ridge-lamellar scales and features a wider range of colours.
