There is also the better-known example of birds, especially robins, whose males guard 'their' territory with comic ferocity - albeit not comic if you are another male robin straying on to the patch. So it is with looking for moths and butterflies; the best tactic when you spot something interesting but it flies off, is often to hang around patiently for a while. They very often return.
I mentioned in the last post the way that optical camouflage in moths can confuse the lens of both eye and camera in the particularly striking case of the Scorched Wing. I referred to the Peppered Moth having the same effect and here are two examples. Something about the patterning must cause the lens to shift its focus about as it tries to make sense of the mixture of black and white. Presumably this has the same effect on moths' great enemies, birds, even though their eyes are very different from ours. But I have always found that movement is the fatal giveaway for a moth resting anywhere near to a bird.
Thanks tio the grandchildren, one Peppered became unusually animated after its night's sleep and I was able to get my final picture, of a different posture. In this, the shading of the wing (I think) helps the lenses to calm down a bit. In any event, what a beautiful creature it is.
