Abstract In temperate climates, winter can be an arduous time for eusocial insects. Survival of honeybee colonies during depends on a delicate balance between hive thermoregulation, managing the food reserves and timing onset new worker bee generation. Winter survival is influenced by several factors, most notably colony size, Varroa mite infestation levels availability stored food. Importantly, climatic conditions floral resources previous foraging season also impact health strength before hibernation. This study, conducted across Europe, examines how landscape composition weather affect colonies. It uses pollen diversity as proxy flower resource quality available days variable to understand their causal relationships survival. We found that landscapes with higher percentages agricultural areas increased collected honeybees in autumn, whereas semi‐natural summer. Spring autumn was main driver success, emphasizing importance diverse health. While we did not find statistically significant effect survival, trends suggest potential influences, warranting further research confirm clarify role seasonal Synthesis applications : Our study highlights critical including comprehensive framework studying suggests increasing plant around apiaries implementing practices enhance significantly improve benefiting even activity, distinct from needs other pollinators.

The decline of pollinators in agricultural environments poses a significant threat to pollination ecosystem services. Wildflower strips are proposed as strategy support pollinator populations and enhance their species richness diversity. We investigated the efficacy flowering plant mixture maintaining aculeate diversity (wild bees, predatory wasps, kleptoparasites) within intensively managed where rapeseed is common rotational crop. Over four years, were counted five times per season using 250 m transect walks. Our results demonstrated that evenness abundance distribution higher sown wildflower strips, whereas mean was greater remnants semi-natural grassland. low assemblage habitat attributed dominance sweat bee Lasioglossum pauxillum, which thrived on mass-flowering concentrated grassland fragments after harvest. conclude enriched with mixtures effectively Furthermore, both preserved patches unmanaged or minimally habitats can essentially contribute services intensive environments.
