Not so sweet:  The secret struggle between honeybees  and native bees

Australia’s native  bees are in trouble —  and the culprit is  buzzing in plain sight.

Feral European honeybees, introduced for honey and crop pollination, are muscling out native species, taking their pollen and leaving them weaker, smaller, and with fewer offspring.

Dr Kit Prendergast, a native bee expert, warns that high honeybee densities — especially in conservation areas — are harming native species already pressured by urbanisation.

Australia is home to  around 2,200 native  bee species, many still undescribed, with new species continuing to be discovered.

Research using bee hotels  in Perth found that in areas  with more honeybees, native bees produced fewer, smaller offspring — and more males — a sign of stress and  long-term decline.

Experts say European honeybees, though often romanticised, are a feral livestock species in the wild and pose a serious ecological threat to native pollinators and biodiversity.
