The Large Carpenter Bees (Xylocopa, Apidae) of the Neotropical Region: Phylogenetics, Classification and Biogeography

open access: yesZoologica Scripta, Volume 54, Issue 6, Page 884-896, November 2025.
ABSTRACT The large carpenter bees of the genus Xylocopa comprise almost 400 species distributed worldwide. Their large body and ability to build nests through woodworking make them one of the most remarkable groups of bees. In the Neotropics, they comprise over 100 species occurring in tropical and subtropical environments including islands in the ...

Multifemale nests and social behavior in Euglossa melanotricha (Hymenoptera, Apidae, Euglossini) [PDF]

open access: yesJournal of Hymenoptera Research, 2012
The nesting biology and social behavior of the euglossine bee species Euglossa melanotricha was analyzed based on the monitoring of eight nests found in man-made cavities and transferred to observation boxes. Euglossa melanotricha females usually construct their nests in cavities in the ground, in buildings, or in mounds.

Combining Distribution Models of Plants and Their Mutualists to Map Gaps in the Knowledge of Ecological Interactions

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim The distribution of species relying on mutualistic partners for reproduction can be constrained by their partners' distribution. Nonetheless, biotic interactions are often overlooked when estimating the distributions of species (e.g., pollinators of a given plant and the proportion of them with their distribution modelled). In the Tropics,

Influence of landscape structure on Euglossini composition in open vegetation environments [PDF]

open access: yesBiota Neotropica, 2017
Abstract The fauna of Euglossini bees is poorly known in savanna regions, making it difficult to understand how these bees use open vegetation environments. The aim of this study was to evaluate the influence of landscape structure on species abundance and composition of Euglossini bees in naturally heterogeneous savanna landscapes.
