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.
18 lip 2011 · Inachis io has isolated-large eyespots on the dorsal surface of its fore- and hind wings. The butterfly has evolved a mechanism wherein, on approach by a potential predator, it flicks its wings open and close, exposing its eyespots abruptly (Blest 1957).
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.
16 lut 2022 · The new study by the NUS team discovered that the development of eyespots on the wings of butterflies relies on the deployment of a pre-existing gene regulatory network that was already being...
7 kwi 2015 · Big spots on butterfly wings actually can mimic the eyes of predators, a new study finds, reviving a partly discredited textbook truth with fresh evidence.
The ventral wing surface is mottled tan, grey, and brown and somewhat resembles tree bark. These patterns help camouflage the adult, while the eye spots protect it from predators that manage to find it.
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.
