Honey bees remove 80% of pollen—leaving native bees with nothing

Feral honey bees, once celebrated for their agricultural value, are now threatening native ecosystems in Southern California by monopolizing pollen sources and overwhelming native pollinators. A new study reveals they remove up to 80% of pollen in a single day, severely disrupting food sources for over 700 species of native bees. Despite their benefits to agriculture, these invasive bees dominate nearly all bee biomass in the region and even produce lower-quality offspring when pollinating native plants. The findings urge conservationists to rethink beekeeping practices, especially near threatened bee populations and natural preserves.
