My female is calling, and i have 3 males that each are having trouble. Male 1 mounts the female, but can't connect his abdomen to hers, ive waited two days and its never happened. Male 2 runs after the female, like hes about to mount, but then he loses interest and flies away. Male 3 just runs away. So irritating! They are all well fed and full, but no mating!!!! Any advice?
