Fluorescent colors in orchid bees (Hymenoptera: Apidae) [PDF]
Neotropical Entomology, 2005 The presence of UV-fluorescent pigments is described for the first time in insects. The clear hairs on terga I, III and IV of Eulaema niveofasciata (Friese) are the only ones among several Euglossina species which fluoresce, supporting recent taxonomic studies which suggested that this endemic species of the Atlantic Forest domain and Eulaema ...

Orchid bee collects herbicide that mimics the fragrance of its orchid mutualists
Florida EntomologistAbstract Male orchid bees store volatile compounds collected from their orchid mutualists and other sources to use in their courtship. Males of a naturalized orchid bee in Florida, Euglossa dilemma Bembé & Eltz (Hymenoptera: Apidae), intensively and habitually collected from substrates impregnated with triclopyr herbicide, most ...

HORNETS FOOLED BY ORCHIDS THAT SMELL OF SCARED BEES [PDF]
Journal of Experimental Biology, 2009 ![Figure][1] Orchids can be highly deceptive. About 10,000 nectarless orchid species deceive insects into visiting them by imitating either the scent of a nectar-bearing flower or, more dramatically, the shape and pheromones of an insect of the opposite sex.

Orchid bee fauna responds to habitat complexity on a savanna area (Cerrado) in Brazil.
Sociobiology, 2016 Habitat structure and complexity may broadly affect the diversity and composition of a variety of fauna in terrestrial systems. Here we investigated responses of orchid bee assemblages to habitat complexity, with the aim of assessing complexity as a ...

An olfactory receptor gene underlies reproductive isolation in perfume-collecting orchid bees
bioRxiv, 2019 Speciation is facilitated by the evolution of reproductive barriers that prevent or reduce hybridization among diverging lineages. However, the genetic mechanisms that control the evolution of reproductive barriers remain elusive, particularly in natural
