The attack was swift and deadly. One of the most formidable predators in Bug Kingdom, the Robber Fly, mimicking a Bumblebee, took the unsuspecting Wasp by surprise in mid-air. There was a brief aerial tumble before they landed. The Robber Fly's bearded face disguised the ordeal of it's paralyzed victim.
The Robber Fly uses it's stabbing mouthparts to inject neurotoxic venom, whilst digestive juices transforms the wasp's inside into a smoothie, that will be sucked up at leisure. The venom is usually harmless to humans, but their bites can be painful.
