Abstract - The species diversity and community structure of trap-nesting bees in the Parque Municipal das Araucárias in Southern Brazil was studied during 2 years. Three different habitats (Araucaria forest, swamp and grassland) were investigated in terms of abundance, richness, diversity and similarity of bee communicites. A total of 120 nests of 11 species were collected. The largest abundance of individuals and species richness was found for the family Megachilidae. The most abundant species were Centris tarsata, Megachile brasiliensis and Colletes sp. Intermediate species were C. tarsata, M. brasiliensis, Colletes sp, Epanthidium nectarinioides, Megachile (Dactylomegachile) sp1, Anthodioctes claudii, Megachile sp1 and Megachile sp2. Megachile (Austramegamegachile) fiebrigi, Xylocopa (Neoxylocopa) augusti and Megachile (Moureapis) sp1 were the rare species. Swamp habitat yielded the greatest abundance and diversity of bee species. The similarity between this habitat and grassland, in relation to their species abundance and also to their species presence-absence, was the greatest.
