Butterfly Learning and the Diversification of Plant Leaf Shape [Frontiers in Ecology and Evolution]

par Frédéric Magné - publié le

Visual cues are important for insects to find flowers and host plants. It has been proposed that the diversity of leaf shape in Passiflora vines could be a result of negative frequency dependent selection driven by visual searching behavior among their butterfly herbivores. Here we tested the hypothesis that Heliconius butterflies use leaf shape as a cue to initiate approach toward a host plant.(...)
