Document Summary
Aposematic coloration are warning signs conveying - i"m dangerous, don"t approach me. Typically found in insects, but also in some reptiles. Mullerian mimicry is copying the coloration of animals that are dangerous or poisonous while being dangerous/poisonous yourself. Milkweed beetle and milkweed bug have warning coloration (brightly red and black) When this caterpillar becomes a butterfly, it also passes on the poison to the butterfly. Viceroy butterflies are mullerian mimics and look alike with monarch butterflies. Batesian mimicry is copying the coloration of animals that are dangerous or poisonous while not being dangerous/poisonous yourself. It consists of a model (the animal being mimicked) and the mimic (animal mimicking) Models have to be more than mimics otherwise predator wont stop eating species if most of species is ok. Hover flies (model) resemble bumblebees/wasps/honey bees/bald-faced hornet (models) yet the hover flies are harmless. Sugar maple boar beetle looks like yellowjacket wasp (model) You don"t have to be brightly colored to be toxic.
