Modifying a valved half-face respirator with a long expiratory hose could maybe reveal whether it's breath.It's a question I've often pondered, especially given that we don't really know that they perceive a face to be a face or a face behind a veil to be a face behind a veil, particularly when combined with a moustache or beard which may be any one of a variety of colours and stragglinesses.
It seems logical to propose that there must be some other trigger and one's breath could be it, perhaps because of the increased CO₂ or moisture levels in the air exhaled. I wonder if anyone has done any experiments in this area? Say, breathing through a "snorkel" of some sort? Or could it be something else? The heat given off by one's head, for instance. Perhaps they're inclined to target the warmest part of whatever they perceive to be a threat?

Certainly colonies respond very differently to being blown on - from moving out of the way calmly to flying off the frames.
