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

Long‐term (1979–2019) dynamics of protected orchid bees in Panama
Conservation Science and Practice, Volume 3, Issue 12, December 2021., 2021 We gathered quantitative data on 33 species of an intact orchid bee community in lowland forest. Our two studies combined included half the months during 50 years' monitoring. Most species increased or were stable, but the declines included some of the most common and, therefore, unthreatened species.

Mechanics of nectar feeding in the orchid beeEuglossa imperialis: pressure, viscosity and flow [PDF]
Journal of Experimental Biology, 2006 SUMMARYThe orchid bee Euglossa imperialis sucks nectars through a slender proboscis. I tested how nectar properties influence this suction pressure and whether ambient air pressure sets the upper limit for suction feeding. Nectar intake rate was measured as a function of sucrose concentration (5-75% w/w),nectar viscosity (2-80 mPa s), and ambient ...

Sociobiology, 2015 Multiple biotic and abiotic variables control the composition, diversity, and temporal fluctuations of insect communities. In particular, the assembly of bee communities is strongly influenced by climatic factors as well as variation in food resource ...

A Preliminary Checklist of the Orchid Bees (Hymenoptera: Apidae: Euglossini) of Ecuador
Psyche: A Journal of Entomology, Volume 2018, Issue 1, 2018., 2018 A checklist of Euglossini in Ecuador is given, including all currently described, valid species collected until 2018. The list has been assembled from museum records, fieldwork cited herein, and literature. The former species lists are nearly doubled here, with 1 Aglae, 23 Eufriesea, 68 Euglossa, 18 Eulaema, and 5 Exaerete, 115 in total with >50 new ...

New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.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 ...

Landscape influence on pollinator population genetic connectivity
Insect Conservation and Diversity, Volume 18, Issue 3, Page 285-302, May 2025.We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...
