Male sleeping aggregation of multiple Eucerini bee genera (Hymenoptera: Apidae) in Chapada Diamantina, Bahia, Brazil

Males of some groups of bees have to find a place outside the nests to sleep, sometimes forming “male sleeping aggregations”. Here we report the first record of “dense” male sleeping aggregation of two different genera of Eucerini bees observed in Bahia, Brazil. We discuss the possible aim of this kind of aggregation as well the plant utilized on aggregate.

某些蜜蜂群体的雄性个体必须在外部巢穴寻找睡眠场所，有时会形成所谓的‘雄性睡眠聚集群’。本研究首次记录了在巴西巴伊亚地区观察到的由两种不同属的Eucerini蜜蜂构成的‘密集型’雄性睡眠聚集群。我们探讨了此类聚集群可能的目的，以及被聚集群所利用的植物。
