Pupae can be overwintered around 10-13º C. Spray them
every 2-3 weeks a little, so they dry easy. In May you can
warm them up, and spray them more frequently. I put the
pupae at a steady temperature around 26-27º C and spray
them every 2-3 days. When the pupae got soft, I put
them into a small rearing cage to emerge. Pairing is very
easy, and should take around 20 hours. Females start to lay
eggs the same night, but it often happens they pair again.
Eggs are very light green, and should be kept in humid
conditions. The best result I got is when they are stored in
larger petri dishes. When small ones used, and no humid,
none did emerge, although I witnessed al pairings. Best to
rear them is on the host plant, not on cut food. I did use
cut food because I didn't have anything else, and it seems
they like a bit of water, but not sure. It is very hard to rear
them in the early instars on cut food, but in later instars 4-5
it won't be a problem. The young caterpillars walk around
very much! They are very beautiful!
