Did you notice the robber fly is preying upon a bee?
Robber flies feed mainly on other insects. (Whew, that’s a relief!)
The fly attacks its prey by stabbing it with its short, strong proboscis injecting the victim with saliva containing neurotoxic and proteolytic enzymes which very rapidly paralyze the victim and soon digest the insides; the fly then sucks the liquefied material through the proboscis.
