Mimic
A mimic is any species that has evolved to appear similar to another successful species in order to dupe predators into avoiding the mimic.
There are two types of mimics:
For example, the Aegeria moth is a Batesian mimic of the yellow jacket wasp[?], because it resembles the wasp, but is not capable of stinging. A predator who would thus avoid the wasp would similarly avoid the Aegeria.
On the other hand, a honeybee is a Mullerian mimic of the wasp, since both share similar appearance and coloring, and both are capable of stinging.
