    Sammanfattning : The red admiral (Vanessa atalanta) is a migratory butterfly that can be found in North America, North Africa, Europe and some parts of Asia. In Europe the main part of the population spend winter in the Mediterranean region and the following spring leave this area to breed further to the north. LÄS MER

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

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

    Sammanfattning : 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. However, empirical evidence of the adaptive value of eyespots, as well as knowledge of butterfly behaviour under the threat of predation, is scarce. LÄS MER

  4. 3. Antipredator defence in butterflies

    Författare :Martin Olofsson; Christer Wiklund; Graeme Ruxton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antipredator defence; Bird; Crypsis; Predator; Predator-prey interaction; Prey-attack behavior; Butterfly; Deimatic behavior; Eyespots; Startle display; zoologisk ekologi; Animal Ecology;

    Sammanfattning : 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. LÄS MER
