The dangerous species (the kinds of living things which have poison and weapons) usually warn surroundings and avoid being preyed on by telling predators that they are dangerous by their colors and appearance. It is Batesian mimicry that makes use of the feature of such dangerous species. That fact had been discovered by Henry Walter Bates (1825-1892) , an explorer in Britain , and called Batesian mimicry after his name.

It is Xylotrechus, one of the insects, that mimic paper wasp. Xylotrechus don’t have toxicity at all. Xylotrechus are counted not as bees but as cerambycidae , and are the target of preys that live on fallen leaves of kinds of oaks. However , mimicking the figure with the very paper wasp’s warning color makes predators mistake themselves dangerous species and protects themselves from natural enemies.

Atrophaneura alcinous Papilio protenor Papilio bianor
Atrophaneura alcinous store poison from the toxic leaves which they ate in their larval stage and cause predators poisoning. Therefore , the bright spots of Atrophaneura alcinous can be said to be the warning color. The butterflies mimicking that Atrophaneura alcinous are Papilio protenor and Papilio bianor. They reproduces the shape of Atrophaneura alcinous’ wings and designs faithfully , and they make natural enemies look as if they were dangerous species with the warning color.
