Pollinators including bees, butterflies, and hoverflies face welfare threats from neonicotinoid pesticides, habitat loss, and disease, with evidence that even sublethal pesticide exposure impairs cognition and navigation.
Pollinator welfare encompasses both physical harm and impaired cognitive function from pesticide exposure. Neonicotinoids at sublethal field-realistic doses impair bees' ability to navigate, learn flower locations, and return to hives - causing individual welfare harm and colony failure. Varroa mite infestation causes physical damage to bees and viruses that shorten lifespan and impair flight. Habitat loss means bees must fly further for food, increasing energetic costs and exposure risk. While bees have simpler nervous systems than vertebrates, their sophisticated cognitive abilities - spatial memory, communication, and learning - mean pesticide-induced impairment represents genuine welfare harm.
