One can only wonder in amazement at how life on earth came to be as it is! Has this incredible buff-tip moth (Phalera bucephala) become just like a silver birch twig through random gene mutation and natural selection (therefore almost by accident)? On the other hand, did the design team in charge of moth development decide that a moth that looked like a piece of twig would be a neat idea? Frankly both theories seem impossible to me and, who knows, there may even be a third reason we humans have yet to discover but for me that is the wonder of nature, so much if it is still a mystery and waiting to be discovered.
The buff-tip moth emerges as an adult and flies at night in June and July and is a common and widespread but because it is so well camouflaged one is unlikely to see it even at rest. It is more common in the south but does occur throughout the British isles.
