Koninginnepage kweek/ mating papilio machaon

Hi
I'm trying to breed with the machaon in a smal glass house, they have come out of their cocoon last week and are now in a habitat with food plants and host plants.
How long wil it take for them to mate and lay eggs?
Is it difficult to breed this species?
And they hardly fly around, only sit on their flowers.........don't they have to be flying around?
