It seems like Müllerian mimicry would be an example of mutualism because both species would end up being eaten less by predators that only have to learn one pattern of warning symbols. But to what extent is Batesian mimicry a form a parasitism? It seems like predators who ended up consuming the harmless species would lose some of their conditioning to not eat prey that resembled it, thus harming the species that is actually protected.
How often might this happen in ecosystems where Batesian mimicry is present? Does the presence of a similar unprotected species cause the protected species to be a more common target for predators?
