Community of Euglossini (Hymenoptera, Apidae) from the coastal sand dunes of Abaeté, Salvador, Bahia, Brazil. The Euglossini community structure was analyzed by attracting males with the scents eucalyptol, eugenol, vanillin, benzyl benzoate and methyl salicylate, and by netting bees on flowers. The samplings took place three times a month along one year from 6:00 a.m. to 6:00 p.m. The scent baits attracted 670 individuals belonging to seven species of three genus. The predominant species were Euglossa cordata (Linnaeus, 1758) (76.6%) and Eulaema nigrita Lepeletier, 1841 (21.8%). Euglossini males visited the scents along the whole year, being more abundant in May and in August. The most efficient fragrance was eucalyptol, attracting 624 individuals of five species. The males abundance fluctuated along the day, being the highest frequency observed between 8:00 a.m. to 10:00 a.m. Forty eigth Euglossini females of four species were netted visiting flowers of 14 plant species belonging to 13 families. Solanaceae and Caesalpiniaceae were the most visited. The species catched on flowers were Euglossa cordata, Eulaema nigrita, Euplusia mussitans (Fabricius, 1787) and Eulaema meriana flavescens Friese 1899. Euglossa cordata was the predominant species on flowers (64.6%), being collected during almost the whole year. Euplusia mussitans was the only species netted on flowers which males were not sampled on the scents.
