Mourecotelles Toro & Cabezas (Hymenoptera, Apidae, Colletinae) currently includes only nine valid species of cellophane bees found mostly in relatively-dry regions of western South America (Chile, Argentina, Bolivia, and Ecuador). In this paper, we describe and illustrate a new species of the genus-M. braziliensis Ferrari & Melo, sp. nov.-based on...

Eugenia uniflora L. (Myrtaceae) is pollinated mostly by bees and there are no restrictions for pollen collection in their flowers. This stimulated us to study the bee diversity on its flowers in two forest fragments in southern Brazil, in August and September, 2012. A total of 826 bees belonging to 39 species and four subfamilies were captured with...

Studies performed using interaction networks have helped in the understanding of mutualistic relationships, allowing for the representation of complex community structure. Conservation of the species that form the networks is a prerequisite for the conservation of the very networks. Pollen analysis allows knowledge of bee visitation history and is...

Este estudo foi realizado em Guarapuava-PR, e investigou a diversidade de abelhas em diferentes cultivares de morango. Foram utilizados oito cultivares com quatro repetições cada, no período de Outubro a Novembro. Foram coletados 252 indivíduos, de 23 espécies, pertencentes a três famílias, Apidae, Halictidae, e Andrenidae, sendo a segunda com o ma...
