This frequency-dependent relationship is an important prerequisite for Batesian mimicry
by increasing the opportunity of learning by predators.

In Batesian mimicry
, the mimic (Pholidichthys leucotaenia) may be quite abundant throughout its distribution if the model (Plotosus lineatus) is extremely venomous and therefore unpalatable, or if the mimic is unimportant as prey (Randall 2005).
This species, like promethea, has very dark males suggesting Batesian mimicry
. Similarly, other silk moth species with diurnal mating, such as Eupackaria calleta, which calls and mates from ca.
If the leg I movement is a means ofpicking up chemical cues we would expect it to be much more random than if it is really a Batesian mimicry
In scientific circles this idea--an edible species benefiting by imitating a noxious one--is known as Batesian mimicry
. It's named after Henry Bates, a mid-1800s naturalist who roamed Brazilian forests collecting butterflies.
may be due to a noxious taste, which has partially been demonstrated for P.
The theory of Batesian mimicry
holds that edible species that look like dangerous species will be protected, because predators evolve to avoid dangerous species--even without previous, real-life, bad dining experiences.
(Bates 1862), where palatable prey resembles unpalatable (or otherwise unprofitable) and conspicuous prey, differs from any other prey-predator dynamic (Endler 1991).
Gilbert (2005) and Stevens (2007) commented on "imperfect mimicry," citing the possibility that it may be an adaptation to combine camouflage with some level of Batesian mimicry
should concealment fail; it is not known whether any of the mimic octopuses are toxic.
That means clicking works both as Mullerian mimicry (two unpalatable species benefiting by making similar sounds that predators can learn by catching either one) and Batesian mimicry
(edible prey borrowing an "unpalatable" signal), says Barber.
For Myrmarachne, the resemblance to the ant model appears to function primarily as Batesian mimicry
. Myrmarachne's mimicry of an aggressive model puts these salticids in a difficult situation.
