Frequently, the stingless bees or Meliponini (Apidae, Hymenoptera) are the most numerous group of floral visitors in the tropical forests, as the Atlantic Rain Forest (ARF). In the ARF, the Meliponini present variation in their diversity at local spatial scale likely associated with differences in vegetation structure and habitat quality. In this study, using honey baits datum, local spatial variation was measured and related to two stages of forest regeneration: intermediate and advanced (or mature forest). Stingless bee diversity (H’) was similar in both forest stages. However, there is spatial variation in species richness with more abundant species (or dominant species) at the intermediate regenerated stage. Response to spatial heterogeneity was also expressed as differential foraging by forest strata, with most bee individuals attracted to honey baits at the higher strata. In contrast, a few stingless bee species likely showed foraging preferences for the low or high forest stratum.
