Creatures like this are proof to me that there is a creator. Can an insect will itself over many generations to look like a leaf so its enemies won’t see it? What consciousness is at work here? A creator’s, or a bug’s? A mistake or intention? 

The atheist and/or evolutionist’s answer is natural selection, the strong, smart or better camouflaged surviving (survival of the fittest) and the others dying until the product is this, but that still indicates a kind of consciousness, the kind of consciousness that adds the deterioration specks of the leaves to its wings, or the reflection of light to an owl’s eye on a butterfly wing. The question is – what is the source of that consciousness?
