A Bush Fly has similar appearances with a Housefly. It grows up to 2-6 mm and is smaller in comparison to the houseflies. The lifespan of these flies is 2-5 weeks. This species of flies are mostly found swarming over the cattle as well as other animals. The female flies lay their eggs in excretes of large animals. The eggs hatch within a day and the larvae leave the food source to pupate in the soil. The adults get attracted to sweat, tears, saliva, and wastes of grazing animals. These flies transmit eye infection to humans and also are responsible for transmitting several other enteric diseases.
