Can a fly be shy?

Damsels and dragons, like other insects, are alarmed when a camera lens approaches and often dart off before the shutter button can be pressed. Yet they invariably circle round and come back to a very similar position.

I would love to know their reasons. Are they simply holding their ground? Or, could they be as curious about us as we are of them? Perhaps they catch their own reflection in the lens and are intrigued.



Whichever it may be, when I came upon this character I couldn't help wondering who was stalking whom?
