When Does a Fly Live?
WouterWhen flies hatch from their eggs, their larvae or pupae develop darker shells and wings. The pupae are inactive for three to six days and then begin developing legs and wings. The pupae have no teeth. When the pupae are ready to emerge, the female flies can breed in less than two hours.
The average lifespan of an adult fly is about 15 to 25 days, but some species can live up to two months. Adult flies can survive for two to three days without food. They also live longer if they can find a cooler location to breed. Female flies need food to reproduce, and this process usually takes 30 minutes to two hours. During this time, the female flies search for a warm, moist place and enough food to lay her eggs.
Many flies feed on decaying organic matter, including plant or animal feces. Others lay their eggs in leaves and stems of plants. Those larvae then convert the plant into a gall, which protects and provides food for them. Another group of flies sucks blood from vertebrates.
It is important to understand the life cycle of flies so that you can take steps to eliminate them. Depending on the size of the infestation, you may have to use pesticides. Using these types of products on your own is not recommended as it can be dangerous. Contact a professional for help.
