Many insects have evolved the survival strategy of mimicry. The hornet's vivid, alternating yellow and black rings, so-called aposematic, or warning colors, co-evolved among many kinds of stinging insects, thus sharing the burden of teaching predators to heed the warning. This is known as M üllerian mimicry. Although it is harmless, the Hornet moth, which has a striking likeness with the giant wasp, is also shunned by predators. This related form of mimicry is called Batesian mimicry.
