Neotropical butterflies in the genus Heliconius are unpalatable, aposematic, and they have undergone a recent adaptive radiation in wing color patterns as a consequence of natural selection for Müllerian mimicry. We are working to identify the molecular basis of the genes that control wing pattern diversity in Heliconius and characterize the evolutionary history of divergence and convergence across the clade. This work relies on combination of high-resolution genetic mapping, fine-scale genome-wide association mapping, comparative analyses of gene expression, and genome editing. Much of this work has been done in concert with an international network of collaborative researchers and has resulted in rich genomic resources for Heliconius butterflies and identification of the key genes regulating wing pattern variation across the clade. Our work also explores the evolution and genetics of mimicry in other diverse butterfly clades, including Limenitis, Hypolimnas, Elymnias, and Papilio.
