Sometimes harmless insects look ferocious, frightening their enemies. One example is hickory horned devil. This large caterpillar scares away its enemies by its appearance. Mimicry is when insects fool their enemies by looking like an insect that is dangerous or bad tasting. A hornet fly has markings of a hornet, but has no stinger. Predators who have had their mouths stung by a hornet do not try to eat hornets again, nor do they try to catch hornet fly!
