Some flies are beneficial and some are pests. Flies are among the fastest flyinginsects.
The body of a fly is composed of a head, a thorax, and an abdomen. The average fly's wings beat about 200 times per minute.
Like mosquitoes, flies cannot bite. Flies that are known as "biting" actually stab sharp mouthparts located in the proboscis into a victim. These flies sip the victim'sblood.
Like other insects, flies have four stages to their life: the egg, the larva, the pupa, and the adult.
Flies carry such diseases as anthrax, rabbit fever, typhoid, cholera, malaria, yellow fever, encephalitis, and sleeping sickness among others.
