mimicry
Heliconius butterflies demonstrating Müllerian mimicry, a form of mimicry where one or more species exhibit closely similar warning systems. In this case, wing patterning and coloration among the species appear very similar.
Aggressive mimicry is a strategy where a predator or parasite gains an advantage by resembling a model that its target does not perceive as a threat. This deception allows the aggressor to approach or lure prey effectively, often described as a wolf in sheep’s clothing.1
Predators utilize this technique in several ways:
- Luring prey: Some predators mimic the prey of their intended victim. For example, anglerfish use a wormlike, fleshy bait on a rod to attract smaller fish, which mistake the organ for their own food and are subsequently eaten.21
- Deception through imitation: Predators may mimic the appearance or behavior of a species the prey trusts. Female Photuris fireflies imitate the mating flashes of Photinus fireflies to lure and consume the males.2
- Camouflage for surprise: By resembling a non-threatening third party, such as the zone-tailed hawk mimicking nonaggressive vultures, predators can bypass the defenses of their prey to launch surprise attacks.2
