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.
The mimicry is Batesian in nature: hoverflies are palatable but hymenoptera are generally unpalatable and may also be protected by stingers and/or armour. Many social wasp species exhibit Müllerian mimicry, where a group of unpalatable species benefit from sharing the same kind of warning colouration. Wasps are decidedly noxious: nasty-tasting ...
Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped. Defensive mimicry includes the well-known Batesian and Müllerian forms of mimicry, where the mimic shares outward characteristics with an aposematic or harmful model. In Batesian mimicry, the mimic is ...
Whether the migration event was a single or multiple occurrence event has a significant effect on how we look at the evolution of mimicry. A history of multiple migrations would suggest that speciation occurred before the evolution of mimicry, meaning mimicry was the result of speciation instead of the driver of speciation.
Brachoria is a genus of polydesmidan millipedes in the family Xystodesmidae inhabiting the Eastern United States. Also known as the Appalachian mimic millipedes, at least 30 species are known, with highest diversity in the Appalachian Mountains, especially the Cumberland Plateau and Ridge and Valley Province.
Müllerian mimicry, a type of mimicry or convergence named after Fritz Müller; Müllerian ducts, which enter the cloaca of an embryo (named after Johannes Peter Müller) Mullerian anomalies are structural anomalies caused by errors in embryonic müllerian duct development; Mixed Müllerian tumor
They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; a well-known example is the eyespots on a peacock's display feathers.
