Keeping Clouded Yellows over winter

[mrossell]

Hi

I am after some advice on keeping some Clouded Yellow Butterflies alive over winter.
I have 10 Pupa that are going to hatch in the next few weeks!
Does anyone have any guidance/Ideas on feeding them when they emerge??
Will they breed during this winter period and lay eggs??
I want to keep them alive and hopefully get them to breed and lay some eggs ready for next spring so that I can photograph them.
I am aware that they will need to be kept in the house for warmth and I am prepared for that with a large cage.


Thanks
Mark
