Abram et al. describe the first example of an animal able to selectively control the color of its eggs. They found that a predatory stink bug tends to lay dark eggs on leaf tops and light eggs on leaf undersides. Darker eggs are more resistant to UV radiation, although surprisingly, the pigment conferring this benefit is not melanin.
