Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility?

open access: yesEcology 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.

Notes on male and female facial patterns in bees (Hymenoptera: Apoidea), with comments on other aculeates [PDF]

open access: yes, 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,

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 875-888, May 2026.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...
