Robber Fly belongs to the Family of Asilidae.  Their size vary from 0.5 cm to 5cm in length. They usually have stiff bristles on the face called mystax.

The name "Robber fly" reflects its notorious and aggressive behavior. They are well known for catching their  predators at flight and mainly  feed on other insects like bees, dragonflies, spiders and even insects that are much more larger than them. They use their bristly legs to catch their prey and hold them around their neck. Then inserting their hypopharynx into the prey, it injects a saliva that contains toxins and enzymes that paralyzes the prey to feed they feed on.
