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.

9 mar 2015 · Developmentally, a pair of intimidating eyespots may be easier to evolve on the dorsal surface of butterflies since both pairs of wings (i.e. left and right) are visible to the predator when the wings are held open.
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. In lab tests, images of butterflies...
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.
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...
1 lut 2003 · Many butterfly genera are characterised by the presence of marginal eyespots on their wings. One hypothesis to account for an occurrence of eyespots is that these wing pattern elements are...
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.
