A number of small species of spiders are capable of flying. These insects are known as ballooning spiders because they use the earth’s electric field to propel themselves through the air. These spiders can travel very far.
The lifecycle of a fly is relatively short. Flies lay eggs in various locations, such as garbage, dead animals, and meat scraps. They hatch in less than a week. They are also capable of breeding within a few hours. The female flies can breed up to 300 times a day. They lay their eggs in decaying matter such as meat, animal waste, and vegetable scraps.
Once the eggs hatch, the larvae feed for a few days. They then develop into pupae. The pupae are hard, black or brown shells. They are inactive for three to six days.
The first instar larvae grow to five mm in length. They moult twice during development. They then begin to develop wings and legs. The second instar larvae then grow to ten mm before shedding their skin.
The third instar larvae then grow to fifteen mm to twenty mm. They then wander off as pre-pupae. These maggots are easily recognized. They have a distinct, triangular structure that looks like a sail.
Once the pupae deflates, the adult flies emerge from the case. They then find their place in a living environment. They may visit corpses, and rotting vegetation wastes, or they may seek refuge in homes.
A common source of flies is mouse poison inside walls. They can also be found in trash cans and in food products. They are particularly prevalent during the summer.
