  4. 2. On the protective value of conspicuous eyespots in Lepidoptera

    Author : Adrian Vallin; Sven Jakobsson; Christer Wiklund; Graeme D. Ruxton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ethology and behavioural ecology; Etologi och beteendeekologi;

    Abstract : Eyespots, circular patterns which resemble the general appearance of the vertebrate eye, are widespread throughout the animal kingdom and are for example, commonly found on the wings of butterflies where they have been proposed to confer protection against predation.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antipredator defence; Bird; Crypsis; Predator; Predator-prey interaction; Prey-attack behavior; Butterfly; Deimatic behavior; Eyespots; Startle display; zoologisk ekologi; Animal Ecology;

    Abstract : Predation exerts a potent selection mechanism and has resulted in a suite of antipredation adaptations encompassing morphological and behavioral traits in prey. In butterflies, several such traits appear to be directed towards birds which are considered as one of their major predators. READ MORE
