- Magnificent magpie colours by feathers with layers of hollow melanosomes
Summary: Stacks of rodlet-shaped melanosomes with an air core acting as dielectric multilayers create the striking bright blue or purple-to-green colours of magpie feathers. The spectral properties of the feathers can be quantitatively explained with optical models based on anatomical data.
- Coloration mechanisms and phylogeny of Morpho butterflies
Highlighted Article: Morpho butterfly wing scales produce their iridescent blue color with more than multilayers. The comparative macro- and microscopical properties of scales fairly agrees with the phylogeny of the genus.
