Müllerian mimicry was first identified in tropical butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals such as poison frogs and coral snakes. The mimicry need not be visual; for example, many snakes share auditory warning signals. Similarly, the defences involved are ...
Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.

Aggressive mimicry compared to a defensive form, Batesian mimicry.The mechanism is often called "Wolf in sheep's clothing".The model for an aggressive mimic can be a harmless species, in which case the 3 roles are separate, or the model can be the prey itself, in which case there are only 2 species involved.
Top: An ant in Mozambique Bottom: An ant-mimicking spider, Myrmarachne Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive.
Pseudocopulation by an insect on a flower is a result of Pouyannian mimicry, named after the French lawyer and amateur botanist Maurice-Alexandre Pouyanne. . [1] [2] This occurs in several orchids, whose flowers mimic the female mating signals of specific pollinator insects, such as bees. [3]
Papilio polytes, the common Mormon, [2] [3] is a common species of swallowtail butterfly widely distributed across Asia. [2] [3]This butterfly is known for the mimicry displayed by the numerous forms of its females which mimic inedible red-bodied swallowtails, such as the common rose and the crimson rose.
Based on phylogenic evidence, it is known that mimicry in the North American admirals was a driver of speciation. An essential condition for the evolution of mimicry was the presence and abundance of unpalatable models. Mimetic evolution also involved direct selection with the model acting as a "starting block" for the mimic to evolve against. [19]
