Bee Killer Fly
Mallophora spp.
Bee Killer Flies are a genus of very large, robust Robber Flies (Family Asilidae) native to North and South America. They are not found in Australia. These flies are notable for their powerful build and their mimicry of bumblebees or carpenter bees. They are formidable aerial predators that ambush other insects, including bees, wasps, and beetles, catching them in mid-air. They then pierce their victim with their strong proboscis and inject a neurotoxic, enzyme-rich saliva that paralyses the prey and liquefies its insides, which the fly then consumes. While they are a fascinating example of mimicry and predation in their native range, their potential introduction to Australia would be a significant biosecurity concern due to the threat they could pose to native bees and the managed European Honeybee industry.
For effective control and prevention, professional pest management is recommended.
