Nothing. Upstream flow stagnates at the leading edge, excess bug splatter there attests to that.

  It can stagnate to the point of bugs not having much of an issue staying on the wing during flight. I remember a case when I was flight training where we had a little spider as a passenger on the top of the starboard wing for the duration of the flight. The little guy didn't fall off until the wing stalled out when we were landing.

    That's a different effect. The region just above the surface is a turbulent boundary layer without much net flow. But it's very thin.
