Gynandromorphy in Eulaema atleticana Nemésio (Apidae, Euglossini)

open access: yesEntomoBrasilis, 2012
A gynandromorph specimen of Eulaema atleticana Nemésio, the first registered in Eulaema, is described. The E. atleticana gynandromorph was captured using an eucalyptol scent trap, in the Mata do Buraquinho Reserve, an Atlantic Forest fragment. The study site has 550 ha and is located in the urban area of the Municipality of João Pessoa, State of ...

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 ...

Generalised bumblebee–flower interactions demonstrate weak floral niche partitioning despite a high bee diversity

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Niche partitioning is one of the key mechanisms allowing species coexistence and is especially relevant in species‐rich communities. For pollinators, morphology is a major axis in which species differentiate their foraging niche, as it influences the match with flower morphology. Bumblebees Bombus spp.

Do sun orchids mimic buzz‐pollinated plants? An experimental test of the adaptive significance of false anthers

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2876-2888, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mimicry implies that an organism gains fitness by resembling a model species, and one example is rewardless plants that attract pollinators by resembling co‐flowering species that provide rewards.
