Pollen samples collected by Frieseomelitta meadewaldoi were analyzed to determine the plants used and their pollen frequency and diversity, and thus test whether there is a correlation between its diversity with temperature or rainfall. In the rainy season, F. meadewaldoi explored 27 floral sources, with greater richness of pollen types from Fabaceae and Myrtaceae. In the dry season, 34 pollen types were recorded, with a great richness associated with Fabaceae, Rubiaceae, Anacardiaceae, and Myrtaceae. Sources of important floral resources and temporary specialization events occurred in both seasons, mainly Coutobea, Eucalyptus, Ligaria teretiflora, Mimosa pudica, Mollugo verticillata, Myrcia, Richardia grandiflora, and Tapirira guianensis. There was no correlation between the diversity of pollen resources and temperature or rainfall, as it depends on the availability of sources of floral resources. Thus, pollen diversity did not differ between months or seasons, as F. meadewaldoi foraging is similar throughout the year.
