No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

open access: yesEcological Entomology, EarlyView.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

Recognition and identification of bumblebee species in the Bombus lucorum-complex (Hymenoptera, Apidae) – A review and outlook

open access: yesDeutsche Entomologische Zeitschrift, 2015
The recognition of cryptic species represents one of the major challenges in current taxonomy and affects our understanding of global diversity. In practice, the process from discovery to acceptance in the scientific community can take an extensive ...

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Complete mitochondrial genome of Bombus breviceps (Hymenoptera: Apidae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
The complete mitochondrial genome of Bombus breviceps, which belongs to the subgenus of Alpigenobombus in Bombus genus, was sequenced. This circular mitogenome is 16,743 bp (83.5% AT) in length, with two rRNA genes, 22 tRNA genes, and 13 protein-coding ...

Bumble bee banquet: Genus‐ and species‐level floral selection by Midwestern Bombus

open access: yesEcosphere, 2023

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

open access: yesEcological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.
