Since a short time I ever and again go down into the microcosm, a very interesting and colourful world. A lot of optical phenomena in the sky can also be found in this little world. The origin of the colours are usually diffraction and interference. Actually it´s no wonder, that these tiny structures are able to bend the light. So it´s probably possible that the bristles of a flies leg get colourful. Well, I think, I should analyze the hairs on my legs, too.. . 😉
The compound eye shows interesting effects as well and the wings anyway. Some flies have seemingly a gold foil between the eyes.
