Behavioural and ecological interactions in Heliconius butterflies
Heliconius butterflies have impressive visual signals, which are under conflicting selection pressures, as they are used in choosing potential mates and defending against visual predators through aposematic coloration. As both selection pressures are likely to be strong, different elements of the signal might be adapted for different receivers. My PhD research is focus in combining sensory ecology with behavioural ecology to explain Heliconius colours signals of different co-mimic pairs. I explore how mimicry in Heliconius is perceived both from the perspective of predators and conspecifics, using visual abilities of both butterflies and birds. Also, I conducted field work experiments, both in insectaries and in the wild. Overall my results highlight important ecological interactions between Heliconius butterflies, their predators and host plants.
