18 lip 2011 · Many butterflies, especially in the family Lycaenidae, have 1 or 2 simple spots or eyespots at the margin of the wing, along with lines radiating toward it, and extensions of the wing close to the eyespot that presumably imitate antennae.
Butterflies and moths with eye-like patterns on their wings are fascinating examples of nature’s ingenuity. These eye spots serve as a defense mechanism, tricking predators into thinking they are staring into the eyes of a much larger and more dangerous creature.
9 mar 2015 · Many butterflies possess striking structures called eyespots on their wings, and several studies have sought to understand the selective forces that have shaped their evolution. Work over the last decade has shown that a major function of eyespots is their ability to reduce predation by being intimidating to attacking predators.
7 maj 2015 · We designed five different treatments corresponding to the following images: an owl with open eyes (OE), an owl with eyes closed (OW), a butterfly with mimetic (real) eyespots (BR), a butterfly with modified (reversed) eyespots (BM) and a butterfly without eyespots (BW).
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.
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 · The four eyes on the wings of the peacock butterfly (Inachis io) are an effective evolutionary defence mechanism, if the insect's wide distribution throughout Europe and temperate Asia is any indication.
