Timema poppensis perfectly camouflaged on its host, Redwood Sequoia sempervirens, California
“A major factor in choosing this image as the winner is that it manages a seemly impossible task: to visualise an immensely long-term ecological process in a single static shot.
A moment’s thought reveals that the evolution of this camouflage may not be simple, because this sequioa is the insect’s host plant. While the insect benefits from its camouflage, the tree (presumably) suffers increased herbivory. This is ecological coevolution along the lines of Batesian mimicry."
