Have anyone seen a fly without wings?

Question

This happened in Puerto Rico when I was 12years old. With only few houses down the hill , I was walking and noticed a dead fish on the ground covered with flies,but the interesting thing was that none of them had wings.

Answer 1

sounds like ants / other kinds of bugs, not flies. ive never seen anything like u described before, sounds scary =/

Answer 2

silverfish

Answer 3

all flies have wings some lose them before death.but no wings??

only wingless flies i know are flightless fruitflies!!

Answer 4

I believe a fly without wings is called a 'walk'.

But in all seriousness, are you sure it wasn't a different type of bug?  Perhaps a flightless beetle or ant.
