Many butterflies we see happily flying around are not perfect specimens! Far from it; they often have chunks missing from their wings; presumably as a result of some lucky escape from a pecking bird. Such imperfections often only become noticeable in photographs, as these two examples show. Yet these are survivors; their camoflague, or behaviour, has been sufficient to allow these individuals to escape predation and to have the possibility of mating and passing on their genes to their offspring (assuming that they are still attractive to their mates!). Such is the stuff of evolution, the predators in this case acting as selectors of the best camoflagued against the existing environment; the strongest or the fleetest. I like to think we are all survivors of sorts, with out aging beauty or imperfect bodies still capable of going on to fulfil our destinies!
