Utilization of floral resources by bees of the Genus Frieseomelitta von Ihering (Hymenoptera: Apidae)
The present study intended to verify which factors (phylogenetic relationship or local ecological conditions) would determine how Frieseomelitta bees use floral resources. The data obtained in the literature on biocenotic studies of Apoidea visiting flowers in Brazil were analyzed, with identification and quantification of floral resources used by Frieseomelitta species in different areas. The phenogram of similarity on use of resources among Frieseomelitta species was compared to the phylogenetic hypothesis proposed for the group. Among the eight Frieseomelitta species registered in 19 studies, F. doederleini (Friese), F. francoi (Moure), F. languida Moure, F. varia (Lepeletier) e Frieseomelitta sp. nov., were collected using resources from 36 plant families. F. doederleini, F. languida e F. varia centralized their activity in Caesalpiniaceae, Malpighiaceae e Anacardiaceae. The similarities and disparities found among areas and Frieseomelitta species reflected the similarities and differences of the vegetation composition in each area. Frieseomelitta bees presented a forage pattern similar to that one presented by other highly social bees, visiting flowers of many plant species, but concentrating their activities in few plant species. Despite the low phylogenetic relationship between F. languida and F. doederleini, they showed a high similarity on the use of floral resource, while F. varia e F. languida, species with high phylogenetic relationship, showed low similarity in the use of resource. Although the data obtained are not conclusive, it indicates that phylogenetic restrictions do not influence the pattern of use of floral resource by Frieseomelitta bees.
