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 · 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 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.
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...
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.
This article reviews the latest developments in our understanding of the origin, development, and evolution of nymphalid butterfly eyespots. Recent contributions to this field include insights into the evolutionary and developmental origin of eyespots and their ancestral deployment on the wing, the evolution of eyespot number and eyespot sexual ...
11 cze 2013 · A Swedish study reports that the butterfly's potential predators in Scandinavia, particularly small birds such as the great tit and the blue tit, have been shown to be frightened by the butterfly's eyespot wing decoration.
