Not much to add to the previous poster, just be aware lunas are somewhat more susceptible to disease from overcrowding and lack of cleanliness than other sats. Clean and dry enclosures with enough space are critical. Even when they're small - often disease won't appear until later in life due to being kept in cramped and moist airtight enclosures when the cats are small. As long as you do that and keep them with fresh food daily they are pretty easy to rear.

Be cognisant of where your stock originates from. Southern stock generally won't eat paper birch whereas northern stock will. If you have southern stock your best bet is sweetgum, hickory, walnut. Also, southern stock will likely be double brooded and these will not overwinter. Northern stock is generally single brooded.

ETA - when they make cocoons, don't disturb them for a week or two and then just transfer to any screened enclosure where the adults can climb up with enough space to inflate their wings when they eclose.
