Abstract
Species richness and seasonality of a bee community were studied in a restinga area in Palhoça, Santa Catarina, southern Brazil. Twice a month during a year, from September 2004 to September 2005, bees were collected on flowers, in flight and with trap-nests. A total of 784 individuals belonging to 64 species of the families Apidae, Colletidae, Halictidae and Megachilidae were collected. Halictidae was the most rich and abundant family, followed by Apidae. Species richness peaks in summer whereas only a few species of Apidae and mainly Halictidae were active in the coldest months of the year. This clear seasonal pattern of activity appears to be a general characteristic of subtropical bee communities in Brazil. Comparison with others studies in restinga of Santa Catarina was made, as also the total apifauna of restinga in Rio Grande do Sul, Santa Catarina and Paraná are presented.
