Moth Mating

[deering3]

Hi folks:
Is there any one good way to get the large saturnids to mate? I have two 
males and one female polyphemus that have emerged, I picked them up and 
attempted to hand pair them as I would with Papilio but this was not going 
to work. I sort of felt like I was mating two cotton balls! Is it the 
dark? Space? What? please help, as I am sure that these poor moths don't 
have a lot of time left in this world.

Sincerely scaled
Mark
