Do Flies Really Vomit When They Land?
WouterThe question, “Do flies really vomit when they land?” can seem rather obnoxious to us, but the reality is very different. It’s likely that the fly is simply airing out some of the food it has just eaten, or blowing off a little bit of water that may have been digested.
Fly’s digestive system is very different from a human’s, which means that they don’t have the mouth parts to chew their food. Instead, they regurgitate their digestive juices onto the food they’ve eaten, which breaks down the food into small pieces. In addition to this, flies also use their mouthparts, or proboscis, to drink their meal. Their feet, however, are highly sensitive, which is why they’re able to taste food.
In the event that a fly lands on your food, it can be a terrifying experience. While the act of a fly landing on food may seem harmless at first, it’s important to remember that a fly can carry bacteria and toxins that could harm humans. The amount of bacteria a fly carries will depend on the type of food it lands on, how long it stays on it, and the strength of your immune system.
Flies aren’t the most appealing creatures, but they’re also attracted to disgusting things. If a fly lands on your food, you may even notice that it poops or vomits. The reason that a fly vomits is because it’s unable to chew, and its stomach is filled with enzymes needed to break down food.
