Final answer:
The concept described is called Batesian mimicry, where a harmless species mimics the appearance of a harmful one to avoid predation, an adaptation related to aposematic coloration.
Step-by-step explanation:
The statement describes a biological concept known as Batesian mimicry, where a harmless species adopts the warning colorations of a harmful one as a defensive mechanism against predation.
This form of mimicry is an evolutionary adaptation that allows non-poisonous or non-harmful species to deter predators by resembling another species that is known to be poisonous or distasteful. Predators, having learned to avoid the harmful species, are thus tricked into avoiding the mimics as well.
Aposematic coloration is a related concept, referring to the warning colors used by animals to signal toxicity or an unpleasant taste to potential predators.
The hoverfly, for example, mimics the coloration of wasps, which are stinging, venomous insects. Despite being harmless, hoverflies gain protection from predators through this deceptive resemblance.
