 It's very common to see male F. canicularis flying in circles in shadows changing direction very suddenly without apparent reason. What determines this change of direction? What do male Fannia see or feel that leads to that behavior?

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
