Unless you also see them in the carboy as well,  I wouldn't worry about it - not much you can do anyway I suppose. 

Isn't it possible that they could just have well found their way into the airlock from the outside?

Is there vodka in the airlock between open air and beer?  If so they can't get in.

The fermenting wort is an anaerobic environment. So even if they got inside they wouldn't survive. You've got nothing to worry about.

Fruit flies lay their eggs on overripe fruit, and are attracted to the smells of fermentation.

It is unusual for me to not have fruit flies in the airlock during the summer.

I get the little buggers in my airlocks often. They climb in through the vent holes in the cap and then drown. Good riddance to them. But it isn't a problem for the beer.

Not to change the subject but seeing that were talking about fruit flies. I'm not sure they just live in over rippen fruit. This year I pick several tomatoes that were just turning red, place them on my counter top to rippen, A few days later they would split open with a white fluid and fruit flies would be hovering over the tomatoes. I've always wonder how they found their way to my garage when my wife was bottling fruit, jams or jellies. Now I Know.
