Population Traits and a Female Perspective for Aglae and Exaerete, Tropical Bee Parasites (Hymenoptera, Apinae: Euglossini) [PDF]
Psyche: A Journal of Entomology, 2019 Size variation of both males and females leads to taxonomic confusion regarding wholly parasitic euglossines. The six most widespread species, Exaerete frontalis, E. smaragdina, E. dentata, E. trochanterica, E.

Diversity and distribution of orchid bees (Hymenoptera: Apidae, Euglossini) in Belize [PDF]
PeerJ, 2023 Background Orchid bees are abundant and widespread in the Neotropics, where males are important pollinators of orchids they visit to collect fragrant chemicals later used to court females.

An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru. [PDF]
Ecol Evol, 2023 We analyzed floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus along a steep elevational gradient in Peru. Results show floral traits and pollinator assemblage variation along the elevational gradient. We examined our results considering two hypotheses: (1) local adaptation to different bee assemblages ...

Evolutionary convergence on hummingbird pollination in Neotropical Costus provides insight into the causes of pollinator shifts. [PDF]
New Phytol, 2022 Summary The evolution of hummingbird pollination is common across angiosperms throughout the Americas, presenting an opportunity to examine convergence in both traits and environments to better understand how complex phenotypes arise. Here we examine independent shifts from bee to hummingbird pollination in the Neotropical spiral gingers (Costus) and ...

Expanded range of eight orchid bee species (Hymenoptera, Apidae, Euglossini) in Costa Rica [PDF]
Biodiversity Data Journal, 2022 The Monteverde region of Costa Rica is a hotspot of endemism and biodiversity. The region is, however, disturbed by human activities such as agriculture and urbanisation.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests. [PDF]
New PhytolHummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Mountain colonization precedes shifts away from bee pollination in Melastomataceae. [PDF]
New PhytolSummary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...

Large-range movements of neotropical orchid bees observed via radio telemetry. [PDF]
PLoS ONE, 2010 Neotropical orchid bees (Euglossini) are often cited as classic examples of trapline-foragers with potentially extensive foraging ranges. If long-distance movements are habitual, rare plants in widely scattered locations may benefit from euglossine ...
