the long thing (very technical) that comes out its mouth goes into the food and it pukes all over it and then sucks some of it back up. 

House flies secrete saliva whenever they attempt to feed, but they don't attempt to feed every time they land. They only do so when they're in need of nutrients, and the chemical sensors on their feet and/or antennae inform them that they may be standing on a source of nutrients.
Strictly speaking, vomiting is the regurgitation of stomach contents, and house flies never regurgitate their stomach contents. What they do is technically spitting (or drooling), not vomiting.
By the way, house flies don't spread disease by spitting on your food, disgusting as that sounds. The disease comes from their feet when they land on your food after they've earlier been feasting on manure or viscera or other bacteria-laden goodies.
Actually, irt's not educational, the flies there have mouths!Cat said:Puffer put that fly down and leave its long thing alone![]()
