Hidden in plain view

I was walking down the lane, stopping to look at the violets, still flashing their purple come-ons from the bank, when I noticed the moth, clamped motionless to the foliage and slightly creased like a withered leaf.

It's an Angle Shades, Phlogophora meticulosa, a common species whose  camouflage can make it difficult to spot. It  has evolved to resemble to a dead leaf  by scrunching its folded wings at rest so as to look crumpled. This type of camouflage is called crypsis; there is an amazing example of it in a gecko here.

One species signalling, one in disguise.
