dc.description.abstractHighly eusocial bees (Hymenoptera, Apidae) flower visitors in a continental sand dune ecosystem from the medium São Francisco River, Bahia, Brazil. A community of highly eusocial bees in sand dunes, covered with caatinga vegetation, in the medium São Francisco River, Bahia (10º47' 37"S and 42º49' 25"W) was studied. The local climate is semi arid and hot, with mean temperature of 25.7 ºC and annual precipitation of 653.8 mm. Censuses took place every two months, from February to December of 2000. The bees were sampled on flowers with entomological nets, from 6:00 a.m. to 5:00 p.m. A total of 2,147 individuals of eight species of Apinae were found, of which Apis mellifera Linnaeus (40.2%), Trigona spinipes (Fabricius) (28.7%) and Frieseomelitta silvestri languida Moure (14.7%) were the predominant species. The diversity was H´ = 1.53 and the evenness E´ = 0.73. The bees were active during the whole year, but there was a significant variation in the monthly abundance of individuals (χ2= 799.55; df= 35; p<0.0001). The daily activity was greater between 6:00 a.m. and 8:00 a.m. The low bee diversity observed is a consequence of the low richness of botanical species and of the small amount of sites for the bees’ nests. The community of highly eusocial bees from the dunes presents organization patterns similar to those observed in other caatinga areas, albeit with some particularities.pt_BR
