A member of the Robber Fly (Asilidea) family, these flying terrors are also known as Assassin flies. Similar to dragonflies, Cannibal flies are voracious hunters who ambush their prey in mid-air. They principally feed on bees, ants, grasshoppers, dragonflies, and other insects. After they’ve caught their victim, Cannibal flies use their proboscis to inject liquefying neurotoxins and proteolytic enzymes into the insect’s body. The fly will then find a quiet spot to feed. After a few moments, all that will be left will be an empty shell.
