Safeopedia explains Batesian Mimicry
Batesian mimicry works to protect the mimic because the model species that is being copied usually has markings that point out to predators of both species that it is dangerous. The model usually has a foul taste or is toxic, and this wards off dangerous predators for the model species. As the mimic copies the appearance of the undesirable species, the predator can be avoided by the mimic.
