Composter
they are wasps with the light changing going through their wings.
lol. if you look closer at the video you will notice as the object enters the screen that there is a light at the back of it. another at the front as it passes. Also keep in mind that building im shooting over is about 2-3 stories high (would have to be a big wasp to have showed up on the camera like that, fying way high up and fast.)
