Integrative approach resolves the taxonomy of Eulaema cingulata (Hymenoptera, Apidae), an important pollinator in the Neotropics [PDF]

open access: yesJournal of Hymenoptera Research, 2022
Species delimitation is a rich scientific field that often uses different sources of data to identify independently evolving lineages that might be recognized as species.

An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru. [PDF]

open access: yesEcol 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 ...

Diversity and distribution of orchid bees (Hymenoptera: Apidae, Euglossini) in Belize [PDF]

open access: yesPeerJ, 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.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests. [PDF]

open access: yesNew Phytol
Hummingbird 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 ...

Males of the orchid bee Eulaema cingulata (Hymenoptera: Apidae) as important vectors of the cleptoparasitic beetle Meloetyphlus fuscatus (Coleoptera: Meloidae) [PDF]

open access: yesApidologie, 2014
Meloid beetles are known by their hypermetamorphic life cycle with active first instar larvae called triungulins found in most species. Most of the larvae in this family feed on provisions and immature stages of bees. The monotypic genus Meloetyphlus is associated with the nests of some orchid bee species, and some of its morphological characteristics ...

First Record of Brazil nut Pollinators Outside Amazon Biome

open access: yesFloresta e Ambiente, 2022
We present the first records of insect visitors and pollinators of Bertholletia excelsa (Lecythidaceae) in a 25 years plantation outside the Amazon biome, flowering and producing Brazil nuts. We installed a platform to observe and photograph the insects.

Orchid bees enhance seed set production of an understory herb in the Western Brazilian Amazon

open access: yesJournal of Pollination Ecology, 2023
Bee pollination is an important ecosystem service related to the maintenance of many flowering plants. We evaluated the relationship between orchid bee foraging time and the density of flowering plants and whether visitation varied according to the sex ...
