Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 654-668, March 2026.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Habitat fragmentation affects plant–arthropod interactions through connectivity loss and edge effects

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Habitat fragmentation is widespread globally, but the effects of fragmentation on populations and communities are often unclear. Because species responses to fragmentation are interdependent, examining how fragmentation alters species interactions may clarify community responses to fragmentation. In a large, replicated fragmentation experiment,

On the Hymenoptera (exclusive of the Anthophila and Formicidae) [PDF]

open access: yesBijdragen tot de Dierkunde, 1913
Our knowledge of the Hymenoptera of the Island of Waigeu hitherto has been based on the material collected by Dr. A. R. Wallace and described by Mr. Frederick Smith in the Journal of the Linnean Society of London, 1863, pp. 6—48. Omitting the bees (5 species) and the ants (27 species) Smith describes and enumerates 27 species of the Families dealt with

Ten Bee Species New to Green Roofs in the Chicago Area [PDF]

open access: yes, 2018
Green roofs increasingly provide habitat for many insects in urban environments. Pollinators such as bees may utilize foraging and nesting resources provided by green roofs but few studies have documented which species occur in these novel habitats. This
