Biotropica, 1985 The solitary or colonial Euglossini (Apidae) are important pollinators of many planes of low and middle elevation, neotropical forests. The bees are wary, rapid fliers, and capable of flying long distances. The tribe is perhaps best known for the fragrance-colleaing activities of males, particularly at orchid flowers (e.g., Dressler 1968, Dodson et al .

A database and synthesis of euglossine bee assemblages collected at fragrance baits [PDF]
Apidologie, 2020 AbstractEuglossine bees are an ecologically important group, which due to their diverse resource needs act as pollinators of many neotropical plants. Male euglossines collect fragrant compounds used in mating displays from diverse sources, including the flowers of orchids and other plants.

Untangling the Complexity of Climate Change Effects on Plant Reproductive Traits and Pollinators: A Systematic Global Synthesis. [PDF]
Glob Chang BiolClimate change is shifting flowering and animal activity times across ecosystems, potentially increasing the risk of plant–pollinator mismatches. Flower production and plant reproductive success showed varied responses to climate change depending on the ecosystem, whereas nectar rewards declined and floral scents increased or changed under warming and ...

Orchid Bees (Hymenoptera: Apidae: Euglossini) in Seasonally Dry Tropical Forest (Caatinga) in Brazil
Sociobiology, 2018 Euglossini bees are important Neotropical pollinators, but there is a lack in the knowledge about this fauna in dry tropical environments. The aims of this study were to evaluate the richness and abundance of euglossine bees in two fragments of ...

Composition of Orchid Scents Attracting Euglossine Bees
Botanica Acta, 1991 AbstractFragrance composition of flowers from 101 plant species, especially orchids, were analyzed. Several compounds, including allo‐aromadendrene, β‐bourbonene, α‐copaene, α‐cubebene, 1,2‐dimethoxybenzene, 1,3,5‐trimethoxybenzene, epoxygeranyl acetate, 7,11‐epoxymegastigma‐5(6)‐en‐9‐one, two γ‐lactones, germacradienol, germacrene D, humulene, methoxy‐
