18 lip 2011 · Butterflies with intact eyespots survived much better than those without; 13 of the 20 eyespotless butterflies were killed, whereas only 1 of the 34 eyespotted ones was killed. This study was the first to convincingly demonstrate that isolated-large eyespots can increase survival.
9 mar 2015 · When the butterfly rests with wings held together, the ventral surface of a single pair of wings (a forewing and a hindwing) are visible, making it relatively more difficult for a pair of large eyespots to evolve on the ventral wing surface.
21 paź 2011 · The deflection hypothesis suggests that smaller ocelli on the wing margin may deflect attacks of visual predators away from the body of a butterfly and thereby increase his or her chances of ...
7 maj 2015 · In this study, we tested whether the intimidating effect of butterfly eyespots is caused by the mere conspicuousness of the spot or by its mimicry of a predator eye. Our results provide clear support for the eye-mimicry hypothesis but not the conspicuousness hypothesis.
Many butterflies, such as this gladeye bushbrown (Mycalesis patnia), have eyespots on their wings. An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways.
27 sie 2021 · Butterflies that bared more forewing eyespots suffered from more intense attacks, leading to a sharp drop in their population. After unleashing mantid insects in a series of experiments, the team compared the extent of damage sustained by butterflies with either two or four eyespots on their forewings.
8 mar 2022 · DOI: Butterfly eyespots evolved via cooption of an ancestral gene-regulatory network that also patterns antennae, legs, and wings. Researchers probe the genetic logic underlying eyespot development on butterfly wings, identifying the origin of a beautiful and useful novel complex trait.
