Where and What Kind—A Better Understanding of Local and Landscape Features in Planning the Urban Flower Meadows for Supporting Bee Communities

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Our multifaceted approach revealed that the mosaics of habitats surrounding urban flower meadows are at least as necessary to support bees as the local features of UFMs. An abundance of bees responded positively to the number of flowering units, the blue and yellow colors of flowers, and increased cover of industrial areas, green urban areas, and ...

The Significance of Genetic Relatedness and Nest Sharing on the Worker‐Worker Similarity of Gut Bacterial Microbiome and Cuticular Hydrocarbon Profile in a Sweat Bee

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
The relationship between cuticular hydrocarbon (CHC) profile and the gut microbiome (GM) is poorly known in bees. In the primitively eusocial bee Halictus scabiosae we found a high rate of nest‐drifting by workers, which leads to a consequent highly variable intra‐colonial genetic relatedness. Genetically closely related workers, even occupying distant

Historical and recent investigations on the bee fauna of Taiwan (Hymenoptera, Apoidea) [PDF]

open access: yes, 2008
The bee fauna of Taiwan was studied intensively in the first half of last century and was based in large parts on the extensive material collected by Hans Sauter between 1902 and 1914. Subsequent studies on bees of Taiwan have only been sporadic.

Microclimate Temperatures Impact Nesting Preference in Megachile rotundata (Hymenoptera: Megachilidae)

open access: yesEnvironmental Entomology, 2020
The temperature of the nest influences fitness in cavity-nesting bees. Females may choose nest cavities that mitigate their offspring's exposure to stressful temperatures.This study aims to understand how cavity temperature impacts the nesting preference

The subgenus Chelostomoides in Argentina (Hymenoptera: Megachilidae: Megachile)

open access: yesRevista de la Sociedad Entomológica Argentina, 2019
A new species of Megachile subgenus Chelostomoides Robertson is described from xeric central-western Argentina. The male of the new species agrees with those of the M. exilis species group of North America, but not the female, which has a highly modifed clypeus and elongate mandibles.
