where do flys lay eggs in a house
Housefly 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 faeces. These soon hatch into legless white larvae, maggots. After 2 to 5 days of development, these metamorphose into reddish-brown pupae, about 8 mm (0.3 in) long. Adult flies normally live for 2 to 4 weeks, but can hibernate during the winter. The adults feed on a variety of liquid or semi-liquid substances, as well as solid materials which have been softened by their saliva. They can carry pathogens on their bodies and in their faeces, contaminate food and contribute to the transfer of food-borne illnesses. In numbers, they can be physically annoying and for these reasons they are considered pests.
Firefly Fireflies hibernate over winter during the larval stage, some species for several years.[clarification needed] Some do this by burrowing underground, while others find places on or under the bark of trees. They emerge in the spring. After several weeks of feeding on other insects, snails, and worms, they pupate for 1.0 to 2.5 weeks and emerge as adults. The larvae of most species are specialized predators and feed on other larvae, terrestrial snails, and slugs. Some are so specialized that they have grooved mandibles that deliver digestive fluids directly to their prey. Adult diet varies: some are predatory, while others feed on plant pollen or nectar. Some, like the European glow-worm beetle, Lampyris noctiluca, have no mouth.
