Ray E. Stanford had a passion for butterflies and made significant contributions to the field through his publications and collaborations. Stanford was a central figure in the development of paper atlases in collaboration with Paul Opler and Harry Pavulaan in the 1990s. These popular paper atlases documented the presence of butterflies in U.S. counties, and eventually led to early web sites hosted by the USGS Northern Prairie Wildlife Research Center (NPWRC). The data complied by the NPWRC are stored in the BAMONA database and appear on the species maps as historical records. The lepidopterist community owes many thanks to Ray E. Stanford.
