    Byrsonima sericea DC (Malpighiaceae) is an important source of oil for restinga bees. Oil-collecting bees are specialized in harvesting oil, which is essential for their survival and persistence. We assumed that the coexistence of oil-collecting bee species in restinga is based in both time and spatial separation at bee harvesting. Therefore, the objective of this study was to test the hypothesis of floral resource partitioning by oil-collecting bees in B. sericea. This study was conducted in a restinga area of southeastern Brazil during the flowering period of B. sericea. Weekly observations and recordings of visitation frequency and interactions between bees on flowers of two specimens of B. sericea were made. Three Centridini and two Epicharitini species were identified as the most frequent visitors to B. sericea: Centris sp1, Centris (Centris) spilopoda Moure, 1969, Centris (Hemisiella) tarsata Smith, 1874, Epicharis (Epicharis) nigrita Friese, 1900 and Epicharis (Epicharoides) picta Smith, 1874. Byrsonima sericea floral resource partitioning for oil-collecting bees was verified in temporal scale (between flowering weeks and between hours of the day) and spatial scale (between plants and between strata). Oil-collecting bees showed most significant differences in resource partitioning use over the weeks of flowering (temporal) and between strata (spatial) of B. sericea.
