Above pictures show the robber fly just captured a planthoppers. Robber Flies are air hunter. They also known as an Assassin Fly. They have piercing mouth-parts and strong legs which can catch prey on flight. They are medium to large size flies with large eyes and necked head. They are active predators on flying insects, unselective in prey species. Their mouthparts are the triangular proboscis  which insert into prey and suck the juice.
