One, most of our ~30 species of horse flies are too big to be prey to most of our dragons. So, would they be intimidated by them? Two, our ~20 species of deer flies tend to attack the head, whereas the horse flies go lower. Putting a "predator" on your hat likely works only for flies in that vicinity. Would a fly recognize a predator that isn't moving? Sounds like a science fair project! It's been a while since I've worked on Tabanids, the family which includes both of these flies, so I may have the 20 and 30 backwards, above. I think I do actually.

The premise is that dragonflies prey on horseflies and this is why. She does not have to use repellent when horseflies are about since she has been doing this. Has anyone else tried this method of control and does it work? I know at the moment that the store in Petite Riviere has dragonfly pins for sale on the basis of this and I would definitely buy one or more of these pins to put on my hat if it does indeed work. Thoughts on this would be appreciated. James R.
