Heliconius butterflies show striking Müllerian mimicry between species. In other words, unrelated species resemble one another because this helps in teaching predators that they are distasteful. We have demonstrated that mimicry plays a key role in speciation. For example, the sister sympatric species Heliconius cydno and H. melpomene differ in their mimetic warning colour patterns, […]

Heliconius erato and H. melpomene have evolved over 20 distinct geographic races that are convergent between the species due to mimicry, offering an excellent opportunity to study the genetic basis of phenotypic adaptation. Different races can be crossed together and show that colour pattern divergence has a relatively simple genetic basis – few genes control […]
What are the origins of biodiversity? There is much we still don’t understand about the evolution of new biological species. Our research focuses on new world tropical butterflies as a model to understand evolution at the population and species level. In particular, we are interested in the predictability of evolution – to what extent do […]
All the best to Marianne and Alison.
