Data from: Every hue has its fan club: Diverse patterns of color-dependent flower visitation across Lepidoptera

This dataset contains RGB color measurements and family-level plant identifications for flowers visited by adult Lepidoptera in the Southwestern Ozarks, USA. Observations were manually curated from iNaturalist and span diurnal and crepuscular flower visits between 2002 and 2024. The dataset includes: flower color data from Lepidoptera visitation records, a control sample of commonly photographed flowers matched for seasonal availability, and a subset of records for evaluating the randomness of flower choices. Flower colors were measured digitally using standardized RGB sampling procedures to assess color preferences across Lepidoptera species.
