How Do Flies Make Babies?

Flies can make babies in the pupa stage, but they are small. A baby fly is only a few millimeters long and is generally whitish in color. Baby flies resemble small worms and are wingless. They crawl around in search of food and a place to pupate. Most species develop their babies in about seven to 14 days.

A female fly will lay hundreds of eggs. Each egg will grow into a fly within a few days. In this way, millions of babies can be produced in a relatively short period of time. Female flies lay eggs in warm, moist places and fertilised by male flies. The process of mating takes about 30 minutes, and the female will then find a spot in which she can lay her eggs.

During the larval stage, flies will lay their eggs on decaying organic material like food waste, carrion, and feces. The eggs are white, about 0.05 inches long, and hatch within eight to twenty hours. These insects do not require parental care. They can even live in the presence of people.

In addition to laying eggs, female tsetse flies can also give birth to live young. They give milk to their larva, which sucks up the milk. This milk is rich in fats and proteins, similar to human breast milk. However, this can be extremely taxing for a fly mother.
