Also, structural color evolves very quickly and easily, even over the course of just a few generations, involving (at least in some cases) structures that are already present to some degree even in species without conspicuous structural colors.

I like the colors and the soft, directional light.

Placing her eggs furter down on the plant stem the female slowly moved deeper down into the water and the male...

Impressive pictures!

Beautiful pictures of interesting objects.
The adult antlion is phantastic!
