When someone visits your house and sees flies everywhere, their first impression of your house is likely to be ruined. Your guests might think your house or lifestyle is dirty. House flies can be the worst menaces to humans due to the hygiene problems for which they’re responsible. Their frequent buzzing and chasing can annoy you considerably. The ways they breed, feed and even move are much different from ours. Knowing the facts below, flies can be quite fascinating features.
The most heavily populated insects in the world are flies. A variety of 30,000 different species of fly exist, of which the most common is the house fly. It is common knowledge that unlike others, house flies don’t bite. They won’t suck blood directly from you unless you have a wound. They love to breed on dirty places and food.
Flies live on a liquid based diet because that is how they are built. They don’t have the mouthparts needed to break the food and chew it. Thus, they drink only liquids. They first disgorge digestive juices over solid food items which break the food into really small pieces. It’s then through their mouthparts, called a proboscis, that they drink their meal.
Did you know flies can taste food with their feet exactly like butterflies? Their strong senses allow them to smell sources from over a distance. The hairs on their mouth parts and feet are used by them to taste. They’ll taste everything they’ll walk on. Their taste receptors, called chemonsensilla, are found on their lower legs and feet.
House flies excrete a lot and they don’t have to bother where they are doing it. As they live on a liquid diet their digestive system moves much more quickly. It’s believed they defecate every time they land somewhere. They can even do that on their own meal. Because of this and their other breeding and feeding habits they tend to come into contact with dangerous bacteria like Escherichia coli and Salmonella. When they contaminate things, particularly the food and cooking utensils, they transfer the bacteria.
Maybe you didn’t realize it until now, but a house fly can walk upside down. Its anatomy allows it to not only walk but climb on many surfaces no matter how they are oriented. Their feet are packed with thick foot pads, called pulvilli. These have tiny hairs which produce a glue-like substance. This substance gives them excellent grip so they can perfectly scale any surface.
The most astonishing fact is that they have amazing eyes and can see behind them as well. House flies have compound eyes. They can have a 360 degree field of view and that means they can see behind themselves. But unlike ours, their eyes can’t move. While they’re on the lookout for danger, they can navigate and see in all directions.
