Recent trends in UK insects that inhabit early successional stages of ecosystems [PDF]
, 2015 Improved recording of less popular groups, combined with new statistical approaches that compensate for datasets that were hitherto too patchy for quantitative analysis, now make it possible to compare recent trends in the status of UK invertebrates ...

No evidence for pronounced mate-finding Allee effects in the emerald ash borer (Agrilus planipennis Fairmaire) [PDF]
NeoBiotaAllee effects are density-dependent barriers that can impact species establishment and population growth, such as through reduced mating success at low population densities.

Ecosphere, Volume 10, Issue 1, January 2019., 2019 Abstract Declines in native bee populations can limit pollination services that support native plant communities and global food production. Mitigating the impacts on pollinators and ecosystems requires conservation actions that promote biodiversity and remain practical for producers.

Notes on male and female facial patterns in bees (Hymenoptera: Apoidea), with comments on other aculeates [PDF]
, 2013 Pallid (frequently yellow) integumental areas characterize faces of many bees and related wasps. Some species lack such markings, others lack them only in females, while others have them in both sexes. A rule applicable to thousands of species is that,

Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility?
Ecology and Evolution, Volume 16, Issue 5, May 2026.Since larger compound eyes and ocelli altogether improve vision, one may expect that insects specialised in chasing very mobile resources possess such morphological optimisation. By analysing 77 species of bees and wasps, we have found that wasps had larger eyes, but not larger ocelli, than bees.

The potential of weeds in arable fields to support pollinator assemblages
Weed Research, Volume 65, Issue 1, January/February 2025.Abstract To what extent are weeds on arable land useful to pollinators in an arable‐dominated landscape? We sampled the weed flora in fields under conventional or organic farming in SE Sweden. More specifically, we noted the frequency of flowering among weeds that scored high on a pollinator index, henceforth ‘pollinator‐friendly weeds’.
