Odor Compound Detection in Male Euglossine Bees [PDF]
, 2018 Male euglossine bees collect fragrances from various sources, which they store and use for as yet unknown purposes. They are attracted, often specifically, to single odor compounds and blends thereof. We used gas chromatography with electroantennographic

Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity
Journal of Applied Entomology, Volume 150, Issue 8, Page 1153-1163, September 2026.ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Pollination of Two Species of Dalechampia (Euphorbiaceae) in Mexico by Euglossine Bees
Biotropica, 1979 The large genus Dalechampia, including over 100 species of great vegetative diversity, has a basically uniform pseudanthial inflorescence. Investigation of two sympatric species in Mexico has shown considerable divergence in pollination adaptations. In D.

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations
Biotropica, Volume 57, Issue 6, November 2025.In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.
