To escape from predators, flies have evolved a highly aerobatic flying style. Instead of turning by flapping harder with one wing than the other, they roll their body to one side and pull up, like a fighter pilot in a high-G turn. Random zig-zags like this make it much harder for birds to get a ‘missile lock’ on them.
