It's possible she was bitten by one and now is afraid of them. I had a Rat Terrier, Sadie Mae Ann Louise, (she was Texan and thus had to have more than 1 name ) that was bitten on the bum by a horse fly when she was just a wee small puppy. The fly drew blood! To her dieing day, she was terrified of the buzzing noise that flys made. As soon as she heard one, she'd scratch at her bum and then sit down on it, to try and protect it. After she got over the initial fear, she'd get up and try to kill the fly. She was a Rattie, fear just wasn't a part of her nature.
