We provide a preliminary list of the diurnal butterflies of El Carmen de Bolívar based on specimens captured between 2015 and 2017 using entomological nets during active searches. Six of the Colombian families of diurnal butterflies were registered. In this study, we provide the distribution of each species throughout the Colombian Caribbean and we confirmed the presence of some species in the region: Emesis fatimella, Eurybia lycisca (Riodinidae) and Urbanus teleus (Hesperiidae). This research contributes to the knowledge of diurnal butterflies in one of the most biodiverse areas of the Caribbean region, which undergoes a progressive transformation of their ecosystems.
