Macroevolution of perfume signalling in orchid bees
Ecology Letters, 2016 AbstractTheory predicts that both stabilising selection and diversifying selection jointly contribute to the evolution of sexual signalling traits by (1) maintaining the integrity of communication signals within species and (2) promoting the diversification of traits among lineages.

Spectral sensitivities of the orchid bee Euglossa dilemma
Journal of Insect Physiology, 2022Diurnal pollinators often rely on color cues to make decisions when visiting flowers. Orchid bees are major tropical pollinators, with most studies of their pollination behavior to date focusing on scent collection and chemical ecology. The objective of this study was to measure their spectral sensitivities to preliminarily characterize color vision in

Function of environment-derived male perfumes in orchid bees
Current Biology, 2023Perfume making in male orchid bees is a unique behavior that has given rise to an entire pollination syndrome in the neotropics.1,2 Male orchid bees concoct and store species-specific perfume mixtures in specialized hind-leg pockets3 using volatiles acquired from multiple environmental sources, including orchid flowers.4,5 However, the function and the

Scaling of Nectar Foraging in Orchid Bees
The American Naturalist, 2007Morphology influences the rate at which foraging bees visit nectar flowers, the quantity of nectar they must consume to fuel their activities, and, consequently, the profitability of flower species. Because feeding time is a major determinant of visitation rate, I used a biomechanical model to examine how energy intake rate (E) varies with sucrose ...

The transcriptomic signature of adaptations associated with perfume collection in orchid bees
Journal of Evolutionary Biology, 2023Abstract Secondary sexual traits can convey information on mate quality with the signal honesty maintained by the costly nature of trait expression. Mating signals are also often underpinned by physiological, morphological, and behavioural adaptations, which may require the evolution of novelty, but the genetic basis in many cases is ...

Correlates of perfume load in male orchid bees
Chemoecology, 2015Male neotropical orchid bees collect volatile substances from their environment and compose complex, species-specific odour blends in leg pouches. These perfumes are accumulated by the males over time and are exposed during pre-mating display. It has been hypothesized that perfumes are indicators of male genotypic quality and that females chose mates ...

Defensive Bee and Wasp Mimicry by Orchid Flowers
2016A variety of arthropods (e.g., flies, spiders, butterflies) are known to mimic bees or wasps as defense from predators (Cott 1940; Wickler 1968; Edmunds 1974; Plowright and Owen 1980; Rothschild 1984; Howarth and Edmunds 2000; Bain et al. 2007; Chittka and Osorio 2007; Penney et al. 2012) (Fig. 61.1).
