What is mimicry

In the evolution of all species of plants and animals have adapted to the environmental conditions. By adaptation include animal behavior, especially the body structure and, of course, color. The latter refers to the means of protection against potential predators, and this ensures the safety of the species.

What is mimicry

A good defense against enemies are different types of body color. For example, patronizing when pigmentation making animals little noticeable on the background of the surrounding environment. However, animals are very often painted in bright noticeable colors that attract attention. This is typical of toxic, scalding or stinging insects: wasps, bees, beetles, Meloidae, etc. Bright pattern are poisonous snakes, non-edible caterpillars that their views have warned of the danger of attacks on them. In addition, this painting is usually combined with a demonstrative behavior, intimidating potential predator. Efficiency cautionary color was the reason for the appearance of naturally occurring species-imitators. A phenomenon in which there is one kind of resemblance to the unrelated, brightly colored other kind, was called mimicry (from the Greek - mimetic). Its appearance is due to the accumulation of beneficial mutations under the control of natural selection in the conditions of cohabitation edible species (simulators) from inedible (models). What does not always simulators used as a model animal: some butterflies in shape, color is very similar to lichen, leaves, caterpillars - on the branches, etc. Or another example, one type of cockroaches similar to the ladybug size, color, spots distribution, and some flies mimic wasps, butterflies edible - inedible, there are many examples. also found mimicry, although much less frequently than the animals in the world Among the plants: some form of weed wiki, the seeds of which are very similar to the seeds of lentil, white dead-nettle resemblance ( "dead-nettle") with the usual nettles dioecious, having scorching hairs. The bodies of some plants in the course of natural selection began to resemble the appearance of insects or objects of inanimate nature. For example, several species of orchid flowers are similar to the female wasps, and thus attract the males that pollinate them. And representatives asclepiad family have tubers, similar to the stones. It's clear that the imitation of nature is justified, since the extermination of individuals exposed to a smaller part as a species serve as a model, and type-wannabe. But it should always be followed very important condition: the number of simulators is required to be less than the number of models that otherwise would not benefit from mimicry.
