Bees feeling the burn

Biological Reviews, Volume 101, Issue 1, Page 279-296, February 2026.
ABSTRACT Fire is a major form of environmental disturbance, and in recent years, due to anthropogenic climate change and anthropogenic land management, we are seeing increases in the frequency and intensity of fires. With bees being an important, diverse group of pollinators that is facing declines globally, understanding how they respond to fires is ...

Wpływ barw pułapek Moerickego na liczebność i zróżnicowanie pozyskiwanych pszczół (Apoidea, Hymenoptera) [PDF]

, 1994
In deciduous and pine forests the effect of white, yellow and Ыие Moericke traps on numbers and sped es diversity of Apoidea was assessed. It was proven that the most useful in forest are white traps.

Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...

A trait‐based framework to understand and predict the response of wild bee functional groups to anthropogenic landscapes

Insect Conservation and Diversity, Volume 19, Issue 1, Page 56-71, January 2026.
Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.

Larvae and Nests of Six Aculeate Hymenoptera (Hymenoptera: Aculeata) Nesting in Reed Galls Induced by Lipara spp. (Diptera: Chloropidae) with a Review of Species Recorded.

PLoS ONE, 2015
Wetland species of aculeate Hymenoptera are poorly known, even though many of them may serve as diagnostic or flagship species in nature conservation. Here we examined 6,018 galls induced ≥1 year prior their collection by the chloropid flies Lipara spp ...

Mixed effects of urbanization on pollination services among four native plant species

Ecological Entomology, Volume 50, Issue 6, Page 1184-1195, December 2025.
We tested urbanization and fragmentation effects on pollination services using four native phytometer species that were deployed across 10 community gardens located in suburban and densely urbanized areas Landscape context generally did not influence pollination; however, for one of four phytometers (Lobelia siphilitica, pictured above) urban cover ...

Tall trees and exotic herbs identified in pollen and nest materials of seven cavity-nesting solitary bee species in Australia

Frontiers in Bee Science
IntroductionSolitary bees are important pollinators yet vulnerable to decline in resource-poor landscapes. Resources for solitary bees may be supplemented by land managers through targeted plantings, however, little is known about the specific plants ...

No evidence for environmental filtering of cavity‐nesting solitary bees and wasps by urbanization using trap nests

Ecology and Evolution, 2022
Spatial patterns in biodiversity are used to establish conservation priorities and ecosystem management plans. The environmental filtering of communities along urbanization gradients has been used to explain biodiversity patterns but demonstrating ...

First Records of the Adventive Pseudoanthidium nanum (Mocsáry) (Hymenoptera: Megachilidae) in Illinois and Minnesota, with Notes on its Identification and Taxonomy [PDF]

, 2019
We report the first records of Pseudoanthidium nanum (Mocsáry) in Illinois and Minnesota in 2016 and 2018, respectively. This represents a relatively rapid expansion since P. nanum was first detected in New Jersey in 2008.

Pollen sterols are highly diverse but phylogenetically conserved

New Phytologist, Volume 248, Issue 2, Page 936-952, October 2025.
Summary Phytosterols regulate cell membrane fluidity and are precursors for plant hormones and secondary metabolites in plants. Insects are auxotrophic for sterols; therefore, they have to consume phytosterols and dealkylate them to cholesterol. Some insects, including bees, which rely on dietary sources, primarily pollen, for sterols, cannot modify ...
