They sat there for the longest time doing nothing, then I hear a scuffle and look up from my computer to see him just manhandling her into position. The whole thing took about a minute and I did see palpal insertion. She tried to kill him, but I got between them and got him back to his own cage in one piece. I can't find any injuries on him, so I'll assume he's okay. (I did give him extra water in case he has a bleeding injury that's too small for me to see).
In the morning Viva gets moved to a quiet spot in the office and we'll hope for an eggsac. I'm thinking of artificially incubating.
