What weighs more a fly or an ant?

Answer 1

Ants and flies are both insects, but that is about as much as they are like each other. Ants are descended from certain kinds of wasps and if you carefully compare the build of an ant and a wasp, you can see that they are very much alike; in fact some kinds of ants, especially the flying ants, look very much like wasps, and some kinds of wasps look very much like ants. Many ants, like many wasps, have stings, and most wasps, like most ants, can bite.

Flies do however differ from wasps, just as humans differ from horses, though both of us are mammals. Flies don't have stings, and they cannot bite, though some kinds, like horse flies and mosquitoes, have piercing mouthparts that they can stick through your skin to suck blood. Ants cannot do that, because their mouthparts are cutting or crushing jaws like pincers.

Flying ants each have four wings like most wasps and most other flying insects, and in a way, so do flies, but the flies are in the order Diptera (which means "two-winged ones"). In fact, flying flies do have four wings, not two, but their hind wings have shrunk into little clubs we call "halteres". When they fly, flies swing their halteres like tiny gyroscopes. They use those "gyroscopes" to keep their balance, and use their front wings for flying, much as we use our hind legs for walking and our front legs (which we call "arms") for balance (among other things).

So you could say that the difference between a horse and a human is much like the difference between a flying ant (or other type of wasp) and a fly.

Answer 2

Depends on the species and the class of the ant (worker, drone, queen). You have horse flies and little gnats and there is a big difference.
