flies of fruit

I have a beef with fruit flies.

Initially when I see a fruit fly I think, yuck, that's a gross bug. But after smashing about the third or fourth I catch on and go on a hunt for the rotting produce that is attracting these nasty insects.

But then I get to thinking how strange fruit flies are. They really do boggle my mind. They mysteriously appear at the slightest hint of over-ripe fruit, but in less than a day of disposing of the fruit, the hovering black bugs have disappeared, only to be seen the next time I fail to partake in my daily fruit.

what do these flies do when fruit is not rotting in my apartment? Which, I can proudly say, is definitely the majority of the time.

Do these bugs migrate from apartment to apartment in search of undesirable peaches, grapes, bananas, apples or oranges? do they hibernate only to be awoken at the scent of overly sweet produce?

Maybe their name sells them short. Maybe some of them don't even like fruit, but because of the family they're born into, they're forced to eat rotten produce. Maybe little Johnny fruit fly is really in love with double stuffed oreos (I mean, who isn't??)
