Iridescence of beetlesby ~melvynyeo

Photography / Macro / Nature

Iridescence is the third way to produce color from reflected light, the first two being conjugated double bonds (eg. pigments, dyes) and metal ions (minerals, gems). Iridescence in insects are largely caused by their shell structure that reflect light in ways such that the reflected light rays interfere constructively or destructively (or some combination in between) with each other. As different wavelengths experience different degrees of amplification or cancellation, different colors result, eg. if the blue wavelengths experience cancellation while red wavelengths experience amplification, red will result. There are apparently various ways this can be achieved, such as multilayer reflectors (eg. very thin layers of chitin) and photonic crystals.

You have no idea how much it bothers me that I can't seem to identify the beetles you post most of the time.

Seven enlarged antennomeres, what looks like what might be a 4-5-5 tarsomere configuration... grrrr, I wish I had my books with me right now, but I left them at my dorm room!

Well, actually all I can see is that there seem to be 4 tarsomeres to the anterior feet and 5 to the second pair, but you can't see the feet of the hind legs.

Wow! Very informative and interesting! I love bugs. There are tribes in the Amazon who use iridescent beetles to create jewelry. It's quite beautiful!
