Some of the common species encountered in our living environment are the common house fly (Musca domestica), bottle fly (Calliphora sp., Lucilia sp.), fruit fly (Drosophila sp.), drain fly and phorid fly.

Flies feed on a variety of food material but most of them prefer the fermenting or decaying organic matter. They also undergo complete metamorphosis process: egg, larva, pupa and adult. During each of the developmental stage, flies show difference in appearance and habit. Eggs are usually laid on or near to the larval food materials. During early larval stage, they prefer foraging on moist or liquid food materials. However, they will crawl to a dried area for pupation. The complete developmental time requires about 6-45 days, depends on the species and conditions (i.e. humidity and temperature). Adults are usually short live (within a month) and therefore most of them will mate shortly after reaching maturity.
