Thermal analysis of butterfly wings
Scientists study the way in which biological structures produce various optical phenomena because this information can reveal more about how some organisms communicate and can offer new structures for possible use in man-made materials. One such organism under study is the Helena butterfly, Morpho rhetenor (family Morphidae), whose blue iridescence results from light scattering from multilayer...
