*Heliconius erato* (above), and *H. melpomene* (below), a pair of Müllerian co-mimics from different sites in Ecuador and Northern Peru. Each species gains protection from the other's unpalatability. Within any site, the two species are excellent co-mimics, but major geographic differences in colour pattern have evolved within each species. This geographic diversity is extraordinary by temperate zone standards: the region (about 600km x 300km) of the Andean foothills from which all these forms within each species can be found is less extensive than New England or Great Britain.

#### James Mallet and [co-workers](/group "Jim Mallet group") study evolution, hybridization, and speciation - mainly in butterflies

#### Methods range from collecting trips in dugouts, field experiments in the Amazon rainforest, population genetic inferences about selection and gene flow, to genomics

#### NB -- *James Mallet is NOT accepting graduate students this year, due to current budget problems at Harvard University caused by budget changes and uncertainty emanating from the Administration.*
