Batesian mimicry and Mullarian mimicry.. Batesian is the mimicing of two or more palatable species that is aposomatic and thus increases the chances that a preditor skips them. Mullarian is the mimicing of unpalatable (eg. you don't want them) organisms and this increases the presence of bad critters in the area so predation is less common for them all. So, in conclusion the Batesian is prob. the model that you are looking at.

Ps. Batesian and Mullarian might be spelled wrong.. Can't remember and I sold the books back.
