About the Life Magnified Set: These 20 stamps were issued to showcase life undetectable by the human eye alone. All 20 stamps picture photographs taken using special techniques and the aid of a microscope. The set celebrates the beauty and complexity of microscopic organisms and parts of organisms, the study of which have had various impacts on humans.
History the stamp represents: Butterfly and moth (Lepidoptera) wings are beautiful, colorful, and delicate structures. To the naked eye, they look like one thin membrane, but when viewed under a microscope, there is much more to them than that.
Lepidoptera wings are made up of a thin membrane supported by a series of stiff veins. These are all covered by a thin layer of microscopic, overlapping scales. Each scale is attached to the wing membrane and varies in shape, even across a single wing. The exact purpose of these scales is still unknown, but scientists have made some observations regarding aerodynamics, temperature regulation, camouflage, visual displays, and waterproofing.
One of the most interesting hypotheses is that scales help moths avoid detection by bats’ sonar. Scientists did an experiment where a scaled wing and non-scaled wing were exposed to sound and discovered the scaled wing absorbed more sound. Despite this, scientists are still unsure just how the scales create this acoustic camouflage effect. Imagine the possibilities once they do figure it out… Submarines could even be outfitted with similar scales to avoid sonar detection! The microscopic world is full of mysteries we continue to uncover. It will be fun to see what scientists find in the future.
