"Each established Asian hornet nest has been estimated to eat around 11kg of pollinators and other invertebrates per year." [https://www.farnhamherald.com/environment/farnham-beekeepers-issue-urgent-asian-hornet-warning-after-sightings-641095]
If a honeybee typically turns the scales at around 100mg, then 11kg = 110,000 bees, approximately two colonies.
