Is mimicry a structural or behavioral adaptation?

Answer 1

Anything that leads to survival and reproductive success is, generally, an intrinsic adaption. If a butterfly were to mimic another butterfly that was poison to it's predators then those self same predators would tend to leave the non-poison butterfly alone as well as the poison butterfly thus leading to survival and reproductive success for the mimic.
