How does an insect know how to hide itself in full view of its prey? What puzzles me is not the fact of camouflage, but the making use of it. Who told this white moth to sit beside the white windowpane divider? And who or what told several gray moths to alight on the weathered cedar boards surrounding the window? It seems obvious to me that genes are involved, but that's about as far as I can get on my own. |
