I was wondering:

Could bubble-blowing be the symptom of a common fly illness--as sneezing and coughing and runny nose can be for a human cold? Or maybe it's a response to a common pesticide?

One of the earlier post mentioned that flies, when blowing bubbles, remain more still and are easier to photograph. Is this a hindered flight response? (I'm not sure if I could run and have a coughing attack at the same time if I had to.)

I know this post is rather after the fact, but . . .
