An insect's exoskeleton (integument) serves not only as a protective covering over the body, but also as a surface for muscle attachment, a water-tight barrier against desiccation, and a sensory interface with the environment. It is a multi-layered structure with four functional regions: epicuticle, procuticle, epidermis, and basement membrane.
No bones about it!

Hi kaykiko, good question!
Flies, like all insects, do not have bones. They do not have an internal skeleton in the way that humans and other vertebrates do. They have what is known as an exoskeleton, which is a hard outer covering. This is why insects will "crunch" when you step on them. Certain soft-bodied insects (such as maggots, or caterpillars) will have exoskeletons which are much softer, but all of them have one. Inside the exoskeleton, the insects do not have any sort of hard structures--they are essentially all membrane and fluid. That's why they're all gooey when you squish them.
The exoskeleton performs many of the same functions that an internal skeleton does, namely, gives the body shape and serves as a point for muscle attachment. It also provides many of the benefits that we associate with our skin, such as exclusion of microscopic invaders and water regulation.
Unlike our internal skeleton, an exoskeleton does not grow with the organism. As the insects eats and gets bigger, it has to periodically shed its old exoskeleton and grow a new, bigger one. Since the exoskeleton provides so much protection, and gives the insect form, the insect is very vulnerable while it waits for its new exoskeleton to harden--they are very soft and easily crushed, picked off by predators, or dessicated (dried out).

Flies (not fly's), like all insects, have an exoskeleton, which means that their skeleton is outside of their bodies, like a shell or a suit of armor.
The do not have bones on the inside (endoskeleton), as other animals do.

The fly is an insect and has zero bones because insects have exoskeletons instead of bones.

Fly's skeletons are on the out side like lobsters.

Flies have hair and nails so I think they must have bones too. I think they have an exoskeleton(like a lady bug) which gives a fixed shape to the body.

Flies do not have calcium based bones like mammals and birds. They do have an exoskeleton based on the compound chitin, like other insects and crabs.

I don't think so. I've never seen any when I swat them.
