Mating preferences act independently on individual elements of visual signals in Heliconius butterflies

The paper tests whether male Heliconius butterflies prefer full wing patterns or individual elements, finding no preference difference when elements are removed, suggesting independent function of pattern elements in mating and speciation.

Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly

This study investigates intraspecific variation in cyanogenic toxicity in Heliconius erato, finding substantial variation and potential for adaptive evolution despite limited dietary influence.
