These psychedelic creatures are jewel beetles, belonging to the family Buprestidae, order Coleoptera. Their color is similar to that of a reflecting CD because light reflects in many directions off of the texture in their cuticle. Their iridescence comes from their cuticle, not from the pigments in their exoskeleton as you might think.
Unfortunately, their metallic beauty is an interest to jewelers, who use their wings to make jewelry. Animal cruelty… Unkind. On a more positive note, scientists have also recently discovered that they can detect forest fire flames up to 50 miles away! It uses tiny pits on its underside to pick up infrared radiation from the flames of a fire. As of now, only this beetle and some species of snakes are known to have this capability.
