The male gonostylus of the orchid bee genus Euglossa (Apidae: Euglossini)
Zootaxa, 2006 Genital characters remain unexplored in Euglossa and they could be of great value in recognizing species and understanding the phylogeny of the group as in other bee genera. We examined the external morphology of the male gonostylus in 49 species of Euglossa belonging to five subgenera and eight species groups.

Diversity and distribution of orchid bees (Hymenoptera: Apidae, Euglossini) in Belize. [PDF]
PeerJ, 2023 Background Orchid bees are abundant and widespread in the Neotropics, where males are important pollinators of orchids they visit to collect fragrant chemicals later used to court females. Assemblages of orchid bees have been intensively surveyed in parts of Central America, but less so in Belize, where we ...

Areas of endemism of orchid bees (Euglossini) in the Neotropical region
ApidologieAbstract Orchid bees are exclusive to the Neotropical region. This study aimed to identify Euglossini areas of endemism (AE) across the Neotropics and to compare them with existing regionalizations. We compiled 4,317 unique occurrence records for 182 species. AEs were identified using NDM/VNDM software with 3-degree and 4-degree grids,

Molecular identification of species of the Genus Euglossa Latreille (Hymenoptera: Apidae, Euglossini) [PDF]
Neotropical Entomology, 2007 Euglossine bees interact with more than 60 plant families of the Neotropical region. The richness and abundance of these bees have been intensively studied in different ecosystems using the methodology of capturing males with chemical baits. Females are poorly known for most of the species and morphological characters for their taxonomic classification

Bionomics and sociological aspects of Euglossa fimbriata (Apidae, Euglossini)
Genetics and Molecular Research, 2009 The nesting biology and the social structure of Euglossa fimbriata were studied based on two original nests found on the campus of the University of São Paulo, Ribeirão Preto, Brazil. Nest 1 contained two inseminated females, 39 sealed cells, one cell being provisioned, and six old and empty cells.

Nonfloral sources of chemicals that attract male euglossine bees (Apidae: Euglossini) [PDF]
Journal of Chemical Ecology, 1993 We present chemical analysis of four rotten or fungus-infected logs that attracted fragrance-collecting male euglossine bees. Eight of the 10 volatile compounds detected have never been found in the fragrances of orchids pollinated by male euglossine bees.

Brazilian Journal of Animal and Environmental Research, 2021 Introducción. Las abejas euglossinas son consideradas indicadoras de calidad de hábitat debido a su sensibilidad a los cambios ambientales, este grupo es fundamental para mantener la estabilidad de los ecosistemas debido a su función polinizadora. Sin embargo, los procesos de deforestación están afectando negativamente a sus poblaciones.
