Butterfly - plant interactions

Andreas Erhardt , Fabian Cahenzli, Hans-Peter Rusterholz, Jovanne Mevi-Schütz, Marcel Goverde


This project focusses on interactions between plants and butterflies in both the larval and adult stage of butterflies. Although interactions between flowers and adult butterflies (picture) affect the population biology of both, butterflies and their nectar plants, this topic has so far recieved relatively little attention.
We aim to identify basic factors affecting these interactions as well as factors relevant for the protection of both butterflies and their host and nectar plants. Since butterflies are particularly threatened in Europe, and since they function as sensitive indicators of environmental change and as flagship species for nature conservation, this work is also of considerable public interest.

Keywords: pollination - butterflies - nectar preference - herbivory
