Why Can’t Flies Get Out?
WouterFlies are a common problem during the summer months. These pests are often drawn to moist areas and rubbish in the home. They also feed on organic matter and recycle dead matter. Though these creatures are a nuisance, they are also a necessary part of our ecosystem. They help recycle dead matter and feed many other creatures.
Flies’ eyes are made up of thousands of individual visual receptors. This allows them to see 360 degrees of the room and a few yards away. The problem, however, is that they have no pupil. This means they cannot control the amount of light entering a room. Moreover, they have trouble distinguishing between different colours. Luckily, they can see polarized light, but that doesn’t help them perceive windows.
The exoskeleton of a housefly is made of polysaccharides. These polysaccharides bind together with other molecules to form the body wall. The material is hard, like some metals, but is also very flexible, making houseflies bounce off walls.
To attract a mate, flies need a common meeting point. For this purpose, they patrol well-defined airspace under landmarks and swat away competitors. They may even settle down in a small spot, ten to thirty centimeters below the ground, to continue patrolling the area.
