The fly eggs hatch into larvae (also known as maggots) that feed on the protein and eventually pupate (cocoon) to become adult flies.
Flies lay eggs in spoiled meat because it is moist. Also once the eggs hatch it provides the maggots with plenty of food to eat.
Houseflies lay their eggs on rotting meat so their maggots have a source of food on hatching.
raw and rotting eggs
Scavenging
Flies are drawn to the rotting material and get inside of it and lay their eggs. When the eggs hatch, there are the maggots. They then feed on the rotting meat.
Houseflies eat sugar, decaying animals, spoiled eggs, food and flesh.
We can cover our food to prevent the housefly from landing on the food and contaminating the food.
Yes they mate and then lay eggs in meat or rotting food which hatch maggots that turn into fly's
By eating our food
Not all egg-laying animals lay "many" eggs; some raptors and penguins, for example, only raise one chick to adulthood at a time. Those that do lay many eggs have young that face high mortality rates from predation, lack of food, or other factors. Only the fittest (perhaps luckiest) survive to adulthood.
Fright, short trip for food, nest of eggs not hatching and the bird will give up.
It depends on what food it is. The fungi will probably get food from the fridge rotting in a day or two but otherwise, I don't really know.
A housefly usually feeds on faeces, open spores, sputum, and moist decaying organic matter such as spoiled food, egg and flesh.
