By using artificial fragrances as baits, we studied richness, composition, abundance and seasonality of Euglossina species in two areas (forest and dune) in the Environmental Protection Area of the Mamanguape River Bar, State of Paraiba, Brazil, between August 2002 and July 2004. Bees were attracted with wads of absorbent paper containing each of the fragrances: benzyl acetate, ionone beta, skatole, eucalyptol, eugenol and vanillin, and captured with insect net. We collected a total of 3,132 males of nine species of Euglossina. On both areas, Euglossa cordata (L.) and Eulaema nigrita Lepeletier were present throughout the year and were the most abundant species in the forest and the first one was the most abundant specie at the dune. Concerning to the composition, the Atlantic Rainforest areas in Paraíba State were more similar among themselves, the same occurring to the dune areas in Paraíba and Bahia States. In the forest, Euglossina species showed higher seasonality, being more abundant during the drier period, specially E. cordata. At the dune, species were homogeneously distributed in the dry and rainy periods.
