The House Fly!
Some facts about House Fly:
The average housefly lives for 21 days.
A housefly can only ingest liquid material. They regurgitate their food to liquefy the food that they are going to eat.
A house fly's feet are 10 million times more sensitive than a human tongue.
Houseflies are major carriers of disease. They are known to transfer over 100 pathogens, including typhoid, tuberculosis, cholera and malaria. Houseflies collect these pathogens on their legs and mouths when feeding on feces, trash and other decaying material.
Flies have over 4,000 lenses per eye (they only have 2 eyes).House fly eyes can recognize even the slightest movements in a full, 360-degree spectrum. This allows the fly to see a far wider range, as well as detect and react to movement at a quicker pace than species with simple eyes. This is the reason that it is extremely difficult to swat a housefly. One tactic that may prove successful is to swat at the fly simultaneously with two objects: this confuses the receptors of the housefly.

If a house fly spots a group of flies, he will join them. That's why granny's sticky fly paper worked so well - a few flies got stuck and soon all the others were rushing over to check out the crowd.
Flies lay up to 3,000 eggs in their lifetime of one month.
Flies only have 2 wings. Most insects have 4. Their wings beat up to 200 times per second and they stop immediately when their feet land.
