Sociobiology, 2019 The fragmentation and habitat loss are the main causes of pollinators decline worldwide, however very little is known about the composition and distribution of neotropical pollinators along continuous micro-environments.

Flower use by late nineteenth-century orchid bees (Eufriesea surinamensis, Hymenoptera, Apidae) nesting in the Catedral Basílica Santa María la Antigua de Panamá [PDF]
Journal of Hymenoptera Research, 2019 A recent restoration of the Basilica Cathedral in Casco Viejo, Panamá, revealed that prior to 1871–1876 female orchid bees (Eufriesea surinamensis) built large nesting aggregations high above the main altar, based on physical evidence dating to a ...

Brazilian Journal of Biology, 2018 The distribution of most species occurs in delimited regions with unique characteristics called “centers of endemism”. In Eastern Amazon is located the Belém Endemism Center (BEC), one of the most intensely deforested in Brazilian Amazon.

Papéis Avulsos de Zoologia, 2019 Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry ...

Sexual dimorphism and morphological integration in the orchid bee brain. [PDF]
Sci RepAbstract Sex-specific behaviours are common across animals and often associated with sexual dimorphism in the nervous system. Using micro-CT scanning we standardized sex-specific brain atlases and tested for sexual dimorphism in the brain of the orchid bee Euglossa dilemma, a species with marked sex differences in social behaviour, mating ...

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]
BMC Evol Biol, 2015 BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Green orchid bee Euglossa dilemma Friese (Insecta: Hymenoptera: Apidae)
EDIS, 2013 Green orchid bees are a quite conspicuous and charismatic species. This is mostly due to their large size and bright metallic-green coloration. They are very fast and agile flyers, and can be seen quickly darting from flower to flower separated by long ...

In euglossine we trust as ecological indicators: a reply to Añino et al. (2019)
Sociobiology, 2021 Orchid bees have been considered as good ecological indicators of habitat disturbances but recently Añino et al. (2019. Sociobiology, 66: 194-197) highlighted reasons why Euglossini role as indicators should be reevaluated.

Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid. [PDF]
Am J BotAbstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

Journal of Evolutionary Biology, 2023 Traits that mediate reproductive isolation between species, such as those involved in mate choice and/or recognition, are predicted to experience stabilizing selection towards the species mean.
