What is beetle wing color?

Beetle wings can come in a variety of colors including metallic greens, blues, purples, golds, and coppers. These colors are due to the light-reflecting properties of the wing scales, which are made of chitin and protein. The color of the wings can also change depending on the angle of light hitting them, making them appear iridescent. The bright colors of beetle wings are often used in mate attraction and to deter predators by warning them that the beetle may be toxic or unpleasant to eat.
