Are house flies just born big? I mean, you never see a small house fly.
True you see some that are slightly smaller but none that you'd call babies. And now I think about it: how do flies reproduce? Eggs?
The little flies that you see around fruit are a different species, drosophila to be specific. We all know that because who hasn't sexed a drosophila in biology class?
And where do they go in winter?
My curiosity is aroused by the fact that our kitchen tap seems to have become a magnet for fruit flies. No, I don't understand it either. But I'm not that interested that I can be bothered to look it up.
