Relatedness and dispersal distance of eusocial bee males on mating swarms
TLDR
Data indicate a highly efficient mating system with minimal inbreeding in this bee species, with a great dispersal capability not previously found for stingless bee males.

[Pollinators of Bertholletia excelsa (Lecythidales: Lecythidaceae): interactions with stingless bees (Apidae: Meliponini) and trophic niche].
TLDR
An analysis of the foraging behavior and interactions of Xylocopa frontalis Olivier and Eulaema mocsaryi (Friese) in the presence of stingless bees in flowers of Bertholletia excelsa, the Brazilian nut showed that the bee collected pollen in a few species of plants, but mainly on B. excelsa.

Monogamy in large bee societies: a stingless paradox
TLDR
St stingless bee species with large colonies, such as T. spinipes, seem promising study models to unravel alternative mechanisms to increase genetic diversity within colonies or understand the adaptive value of low genetic diversity in large insect societies.

Climate Warming May Threaten Reproductive Diapause of a Highly Eusocial Bee
TLDR
It is found that ∼36% of the southern Brazilian P. droryana population may be active during the expected milder winter months in 2080, and in this scenario, there may be a larger demand for pollen and nectar for that bee species.

Diapause in Stingless Bees (Hymenoptera: Apidae)
TLDR
The objective of this review is to give an overview of the current knowledge about diapause in stingless bees and future perspectives of study on Plebeia Schwarz species because this behavior has been observed mainly in these bees.

Congregation Sites and Sleeping Roost of Male Stingless Bees (Hymenoptera: Apidae: Meliponini)
TLDR
It is reported for the first time the substrates used by stingless bee males for resting at night, that at least one species forms large sleeping roosts composed of hundreds of individuals, and that sleeping roos are not reused on subsequent nights.

Eusocial bee male aggregations: spatially and temporally separated but genetically homogenous
TLDR
It is concluded that T. angustula males randomly disperse within a population looking for mating chances rather than settle on a distinct male aggregation, which seems to contribute to the reduction of inbreeding in this species.

Interactions between carpenter bees and orchid bees (Hymenoptera: Apidae) in flowers of Bertholletia excelsa Bonpl. (Lecythidaceae)
TLDR
Testing the hypothesis of antagonism between two solitary bee species of the family Apidae, Eulaema mocsaryi and Xylocopa frontalis, visiting the Brazil nut flowers in a central Amazonia agricultural area found neither of the species manipulated flowers recently visited by opponent species, and there were practically no antagonistic interactions between them.

Temperature Rise and Its Influence on the Cessation of Diapause in Plebeia droryana, a Eusocial Bee (Hymenoptera: Apidae)
TLDR
The data suggest that the levels of predicted climate warming in the geographic range of P. droryana over the coming decades will probably result in these populations abandoning diapause behavior, which has important implications regarding the ecological service of crop and wild plant pollination provided by this species.
