"Fun Fly Facts" Let's learn something about fly cause all I know is that they can fly hahaha. According to my study, naks brainy yarn lol. 1. They multiply quickly, maybe that's why we always see them anywhere. I already seen their eggs though I don't know how it becomes fly hehe. 2. They don't have teeth. Meaning they don't chew their food. Mostly they eat liquid, they only spit saliva to dissolve solid food. They also taste with their feet which is pretty cool. 3. They poop every time it lands, they do it also even the place where they eat ( excuse to those who are eating hehe). 4. Their life expectancy is 15 to 30 days approximately. It depends on the condition of surrounding and temperature. It can be short or long. Some see them as pest and dirty but every insect and creature also has a purpose in our nature. @Snowver
