First record of the orchid bee Euglossa imperialis Cockerell, 1922 (Hymenoptera, Apidae, Euglossina) in Mato Grosso do Sul state, midwestern Brazil [PDF]

open access: yesCheck List, 2018
The occurrence of Euglossa imperialis Cockerell, 1922 is recorded for the first time in Mato Grosso do Sul, Brazil. This paper extends the distribution of the species by about 800 km west of the São Paulo state, its nearest record.

New and old records of Euglossa imperialis Cockerell, 1922 (Apidae, Apinae, Euglossini) for the Amazon rainforest, Cerrado, and Pantanal of Mato Grosso, Brazil [PDF]

open access: yesCheck List, 2020
Euglossa imperialis Cockerell, 1922 has recently been catalogued in the Cerrado of Mato Grosso do Sul, Brazil, and here we add both new and old data obtained from expeditions conducted in 10 municipalities of Mato Grosso since 2002.

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.

Three‐dimensional visualization of ocellar interneurons of the orchid bee Euglossa imperialis using micro X‐ray computed tomography [PDF]

open access: yesJournal of Comparative Neurology, 2017
AbstractWe used contrast‐optimized micro X‐ray computed tomography (mCT) to trace the profiles of the full complement of large ocellar L‐neurons in the male orchid bee Euglossa imperialis. We find that most L‐neurons collect information from either the dorsal or the ventral retinae in both median and lateral ocelli, with only three neurons associated ...

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 ...

Evolution of five environmentally responsive gene families in a pine-feeding sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae). [PDF]

open access: yesEcol Evol, 2023
We examine the predictability of gene family size changes in the pine tree specialist Neodiprion lecontei. Overall, our results are consistent with predictable gene family expansions and contractions in response to novel selection pressures. Abstract A central goal in evolutionary biology is to determine the predictability of adaptive genetic changes ...

Effects of landscape, resource use, and body size on genetic structure in bee populations. [PDF]

open access: yesEcol Evol
Quantifying genetic structure and levels of genetic variation are important to predicting the ability of populations to persist in human‐altered landscapes and adapt to future environmental changes. We assessed genetic diversity and genetic structure for seven Euglossine bee species that vary in resource specialization and body size.

Age-dependent perfume development in male orchid bees, Euglossa imperialis

open access: yesJournal of Experimental Biology
ABSTRACT Male neotropical orchid bees concoct complex perfume blends by collecting exogenous volatiles from various sources, including orchids. These perfumes, stored in specialized hind-leg pouches and released during courtship, serve as inter-sexual signals.

Large carpenter bees show high dispersal in a tropical semi-arid region susceptible to desertification. [PDF]

open access: yesEcol Evol
This study examines the genetic status of native carpenter bees in a Brazilian region vulnerable to desertification. Employing a population genomic approach, we found low genetic diversity with high homogeneity across populations, even over distances exceeding 300 km.
