Debunking wasp pollination: Wasps are comparable to bees in terms of plant interactions, body pollen and single‐visit pollen deposition

open access: yesEcological Entomology, Volume 49, Issue 4, Page 569-584, August 2024.
We challenged historical assumptions by comparing bees and wasps by (1) their role in a community, (2) body pollen carriage and (3) single‐visit deposition on the plant species complex Solidago canadensis. We found bees and wasps (1) overall visit different plant communities, (2) have comparable body pollen carriage in some families and (3) deposit ...
