How on earth have these things not died out yet? There has been one flapping about my room all day, hitting into every wall/piece of furnature it can. It managed to lose a leg so it's going about with 5 which must have off balanced it or something because it can only seem to fly in helices. It's flapped its way into my face numerous times and now it has managed to get itself stuck on the top of my wall, I have no idea how.. It's dangling by one leg and it has another two stuck between its body and the wall and it can't seem to free them. I don't even understand how they can eat or what they eat.. I can't see them managing to hunt anything and ive never seen them land on a plate I may happen to have lying around with some leftovers. I'm pretty mad, I've had an onslaught of at least one sneaking it's way into every room in my house every day for the past two weeks. Crane flies; How haven't they died out? What do they eat? How do they eat? How do you get rid of them/keep them out?
