Amazing Beautiful Owl Butterfly
Named after their huge eyespots on their wings, which resemble owls’ eyes, the owl butterflies are found in the rain forests of Mexico, Central, and South America.
Owl butterflies are very large, 65–200 mm (2.6–7.9 in), and fly only a few metres at a time.
Due to this, their avian predators have little difficulty in following them to their settling place.
However, the butterflies preferentially fly in dusk, when not many avian predators are around.
According to the Batesian mimicry theory the pattern on the wings of Caligo resemble the head of a predator like a lizard or an amphibian.
It should deter predators while the Owl butterfly is resting, feeding, mating, or emerging from the pupa.
The role of eyespots as antipredator mechanisms has been discussed since the 19th century.
Several hypotheses are suggested to explain their occurrence.
In some butterflies, particularly Satyrinae (such as the Gatekeeper Butterfly and the Grayling), it has been shown that ocelli serve as a decoy, diverting bird attack away from the vulnerable body, and towards the outer part of the hindwings or the forewing tip.
