Robber Fly

Description:

The Robber Flies are air hunter. They also known as an Assassin Fly and Bee Killer. They have 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. They even prey on web weaving spiders. Their mouth parts are the triangular proboscis which insert into prey and suck the juice. Most Robust flies are with noticeable "beard" of setae around the face. It is believed that they serve as protection to their face from damage by their prey.

Habitat:

Female robber flies deposit creamy colour eggs on plants or in gaps within soil, bark, or wood. Egg-laying habits are different depend on species and habitat. Most species lay eggs in masses and are covered with protective coating. Robber fly larvae live in the soil or in rotting wood. Larvae are also predators, they feed on eggs, larvae and other soft-bodied insects.
