Seen yesterday (October 10) in Southern Ontario (near Muskoka), near a lake. Maybe 0.5cm in size or so, during the afternoon.

Hundreds of these little bugs seem to be holding or attached to a curly white piece of fluff each and swinging them back and forth wildly.

What are these? And what are they doing?
