Alarming Eyespots Section 1.6 described how a peacock butterfly will, when threatened, open its wings to reveal two huge eyespots that are hidden when the butterfly is a t rest. By one hypothesis, eyespots frighten a predatory bird by mimicking the eyes or the bird’s predators. Alternatively, the sudden appearance of the spots may act by simply startling the bird. To differentiate between these two possibilities, Martin Olofsson presented peacock butterflies with or without eyespots painted over to domestic chickens. He then recorded whether the chickens gave an alarm call that is normally given upon sighting a ground predator. FIGURE 43.9 shows the results.

FIGURE 43.9 Response of domestic chicken to the defense display of a peacock butterfly (shown above). Butterflies were with or without eyespots painted over. All chickens were previously unfamiliar with these butterflies.

Does this data support the hypothesis that butterfly eyespots frighten birds by mimicking their predators?

Summary Introduction

To examine:  Whether the hypothesis supported that butterfly eyespots frighten birds by mimicking their predators.

Concept introduction:  Aggressive mimicry is a kind of mimicry in which the predators or parasites share the similar signals to prevent themselves from the predators. This makes the deceptive communication through the predator mimicry. This reduces the harmful interaction between the prey and predators.

Explanation

Organisms defend themselves using the aggressive mimicry like peacock butterflies. They open their wings to reveal their large eyespots that are hidden when the butterfly is at rest. The hypothesis on the conspicuousness on predators mimicry states that the frighten predators mimic the eyes of the birds’ predators to prevent themselves from the risk of hunting. Person R presented peacock butterflies with or without the eyespots painted over the domestic chickens. They also recorded whether the chicks gave an alarm call to sighting the predator.
