We have all witnessed it, one window open the other closed. Does anyone have a theory why the fly always tries to get out of the closed window?
Firstly, the fly is not really trying to get out of anywhere - I doubt the fly is actually aware it is in a room, or that it has any reason to wish to get out of it.
Secondly, are you sure that the flies do (in the first instance - which I will explain later) more often fly against a closed window than an open window. What I mean by 'in the first instance', is that a fly flying against an open window, will quickly exit, and will be lost from sight. A fly doing the same thing against a closed window, will not exit the room, and so it it continues to repeat the same flight pattern, will more likely come to your notice. It does not mean that more flies will initially decide to fly against the closed window, only that once they start flying against one window or the other, the one's flying against ad oipen window will quickly be lost from sight.In cooler weather, I see no reason that a fly would wish to fly out into the cold outside. On the other hand, it may be that the fly is attracted by the light coming through a closed window (that does not let in the cold), or may be attracted by the condensation on the window, or the particular air currents around the window.As far as I am aware, unlike bees, ants, or wasps; flies do not have a home to go to; and the inside of a house is probably a better source of warmth and food than anything the outside world has to offer.
