The term “aposematism” was first coined by the evolutionary biologist Edward Bagnall Poulton. It is derived from the Greek for “away” and “sign”, and relates to how insects may ward off predators by smell, or visual signals. Bright colours in adult insects have a role in sexual attraction but there was a debate as to why bright colours might be used in the non sexually reproductive larvae, and Alfred Russel Wallace proposed that bright colours could advertise the unpalatable nature of the caterpillars to experienced predators. Aposematic colour patterns are found throughout the insect world, from black and yellow-striped wasps to black and red, bitter-tasting ladybird beetles, or brightly coloured, poisonous tropical butterflies.Synonymes: Aposematic colour patterns
