The Bee Killer Robber Fly is a large, gray, bristly robber fly that regularly captures and eats honey bees and bumble bees in mid-air — a remarkable feat given the bee's defensive stings. It injects paralytic saliva with its stout proboscis before consuming the contents. It frequents sandy open areas where it watches from low perches and launches fast aerial attacks.
