As I was walking home, this fly flew laps around my head despite the wind blowing hard! Couldn't get rid of it!
Even though the fly is small, the wind seemed no problem to it! It's way to strong for Microlight flying.
I have been told that small insects and flies actually swim through the air, because to them, the air is very thick
If that's true, they are very good at it because they can fly in strong wind and change direction instantly.... I guess very little inertia to deal with and plenty of air friction!
