Under natural conditions, there are several species of parasitoid wasps that lay their eggs on fly pupae, killing the pupae as the parasitoid larvae develop. Some of these parasitoid wasps may be purchased from commercial breeders and released at locations on the animal facility to augment natural populations of these parasitoids. Several species of beetles and mites that prey on fly eggs and larvae are also active under natural conditions. Entomopathogenic fungi that kill flies are also common on animal facilities.

Moreover, houseflies are highly mobile creatures capable of traveling several miles from their birthplace during their short lifespan. This means that the fly buzzing around your lunch could have been feasting on garbage or animal waste just moments ago. Houseflies don’t have teeth; instead, they regurgitate digestive enzymes onto the food to dissolve it before sucking it up again. In doing so, they leave behind traces of whatever was in their gut – which could include various bacteria and pathogens from rotting organic matter they previously feasted on.
Environmental Impacts: How Temperature, Humidity, And Other Factors Affect The Lifecycle
In addition to being attracted to our food, houseflies also seek out moist environments for breeding purposes. Common household items like damp mops or buckets of water can serve as ideal breeding grounds for these pests. Even pet waste left unattended in your backyard can quickly become a thriving housefly nursery. The emergence of an adult housefly from its pupal case is truly a spectacle to behold! It pushes its way out using an inflated pouch on its head called a ptilinum which deflates shortly after emergence.

Life Cycle and Description (Back to Top)
Visual representation is a powerful tool that can significantly enhance our understanding of complex processes, such as the life cycle of a housefly. It provides a clear and concise overview of the process, allowing us to visualize each stage and understand how they are interconnected. While the above paragraph provides a brief overview of the life cycle of a housefly, it’s crucial to delve into more detail to fully understand this intricate process.
Like the rest of the insect world, males and females do not stick together after mating and, unlike nesting insects, females do not care for or protect eggs. Females simply leave the eggs where they will be safe from predators and have plenty to eat upon hatching. Male vs Female To attract a mate and begin the reproductive process, the female house fly produces a pheromone called muscalure.
Feeding occurs in the larval stage, and the wasp eventually emerges as an adult. Lateral view of the head of an adult house fly, Musca domestica Linnaeus. However, despite their seemingly insignificant presence, houseflies play crucial roles in our ecosystem. They aid in decomposition and nutrient recycling but also pose health risks by potentially transmitting diseases. Human interactions with houseflies are inevitable, given their propensity towards residential areas and food sources.
In extreme cold or hot conditions, houseflies may not survive at all. The selection of the egg-laying site is crucial for the survival of her offspring. Female houseflies are attracted to damp, decaying organic material such as compost heaps, garbage bins, or animal feces. Such places provide not only a safe haven for the eggs but also an abundant food source for the larvae once they hatch. In the first section labeled ‘Egg’, picture tiny white oval shapes clustered together. Houseflies lay their eggs in decaying organic matter which provides food for the soon-to-be larvae.
However, interior garbage rooms and compactors provide a suitable environment for house fly breeding sites and should be checked. If the breeding site is not thoroughly cleaned or removed, these pests will continue to be a problem. The eggs hatch into larvae, also known as maggots, which range in size from about ¼-3/8” (7-10 mm) long.
The chemicals you use to treat your lawn can be dangerous, though. These are poisonous chemicals if ingested and can be especially dangerous for pets and children that play on grass. The larvae leave brown patches in the grass as they feed on the roots and cause the grass to diet.
Before pupating, the larva migrates to a drier locality at the edge of its breeding habitat. Depending on temperature and humidity, the adult emerges from the pupal case in three days to four weeks. The larva goes through three instars and a full-grown maggot, 7 to 12 mm (1/3–½ in) long, has a greasy, cream-colored appearance. High-moisture manure favors the survival of the house fly larva. The optimal temperature for larval development is 35°C to 38°C (95°F to 100.4°F), though larval survival is greatest at 17°C to 32°C (62.6°F to 89.6°F).
The female housefly usually mates only once and stores the sperm for later use. She lays batches of about 100 eggs on decaying organic matter such as food waste, carrion, or feces. After two to five days of development, these metamorphose into reddish-brown pupae, about 8 millimetres (3⁄8 inch) long. Adult flies normally live for two to four weeks, but can hibernate during the winter.
Maggots are gregarious animals and travel around in 'maggot masses'. Their digestive activities are so intense that the corpse heats up in the vicinity of a maggot mass, sometimes reaching 53 celsius. It can get so hot inside a maggot mass, that centrally located maggots have to migrate to the edge to cool down. However, the heat is a bonus, because it increases the rate of putrefaction, and the rate of digestion. The housefly’s transformation offers an insightful look into the adaptability and resilience of these creatures that are so common in our surroundings yet often overlooked. Starting with size and appearance, houseflies are generally smaller than blowflies.
