Overview

Brief Summary

Introduction

The "owl butterflies," so called because of the large eyespots on the ventral surface of the hindwing, which when presented upside down with the wings spread suggest the head of an owl. It is not evident that the butterflies exhibit a behavior that would present such a view to potential predators.

Owl butterfly

Not to be confused with Hamadryas (butterfly).

An owl butterfly is a butterfly, in the genus Caligo, known for their huge eyespots, which resemble owls' eyes. They are found in the rainforests and secondary 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 meters at a time, so avian predators have little difficulty in following them to their settling place. However, the butterflies preferentially fly in dusk, when few avian predators are around.[1] The Latin name may possibly refer to their active periods. Caligo means darkness.

Some owl butterflies form leks in mating behavior.[2]

Species[edit]

Listed alphabetically within groups.[3]

There are some 20 species in this genus, which can be divided into 6 groups that might constitute subgenera. Some species are of uncertain placement with regard to these groups, however:

Functions of the wing pattern[edit]

The underwing pattern is highly cryptic. It is conceivable that the eye pattern is a generalized form of mimicry. It is known that many small animals hesitate to go near patterns resembling eyes with a light-colored iris and a large pupil, which matches the appearance of the eyes of many predators that hunt by sight.[citation needed] The main predators of Caligo are apparently small lizards such as Anolis.[citation needed]

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 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.[5] 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.

Research of Stevens et al. (2008), however, suggests that eye-spots are not a form of mimicry and do not deter predators because they look like eyes. Rather the conspicuous contrast in the patterns on the wings deter predators.[6] In this study, however, the influence of surrounding forms, like the head region of a predator, was not tested. Also the question why animals evolved such complex imitations of other species is left unanswered.
