The Clearwing Moths, Family Sesiidae, are a classical example of mimicry. They are day-flying insects who have come to resemble, sometimes to a remarkable degree, various hymenoptera. As Tony Simpson explains, this is thought to give them protection, particularly against avian predators. They resemble wasps not only in appearance but also in their flight, movement and behaviour.
