Inactive A. atropos

Hi, I'm trying to mate A. atropos, so for 3 days, 2 males and 1 female are in a cage with about 25°c but they are inactive even the night, they stay at the same place.
I tried to feed them but no more activity...
They fly only when I disturbe and the female doesn't wants to attract males.
Does someone know the behavior of this species in captivity and some advices to get a mating ?
Thanks !
