This website provides interactive maps for visualising the phenotypes and geographic distributions of heliconiine butterflies, along with a portal for downloading the underlying data. Clicking on a point locality links to a representative phenotype selected from either www.butterfliesofamerica.com or Michel Cast's website. This dataset was first published in Rosser et al. 2012, and the data available here include new records and an updated taxonomy. The original .jpegs and .pngs presented in the 2012 paper are still online here. Feedback, queries and data submissions to Neil Rosser (neil_rosser[at]fas.harvard.edu).
