Recently I learned something new, I had a pair of Citheronia slpendens copulate and the female laid eggs.
I kept some, and sold the rest, what was a surprise is the short amount of time it took the ova to hatch,
even being kept at my room temperature of around 72- 76 f.
Nine days. Perhaps that is typical for all Citheronia, one time I had some regalis ova hatch in the
post, the seller, (unnamed) was partially at fault being too slow.
Something to consider when dealing with Citheronia, despite my classified post, 2 persons from the EU
asked for ova, I'm only going to say that it's pretty clear that the eggs would not have made it there
in the regular post.
I'll let you know if they eat peach leaves..

Asian Papilio eggs hatch in 5-7 days, so it is impossible to send eggs of those. Do US Papilio eggs hatch as quickly?

Adam.

Well, it took a long time. I would have never guessed.
We do have cooler temperatures here on the Oregon coast,
but I never expected the following-
A female Papilio rutulus laid ova on my Salix babylonica,
I watched her flit about and found 1 egg, I sleeved it on July 11,
a few days ago I checked the sleeve and the egg was still on the leaf,
so I brought it indoors.
The caterpillar is eating it's egg shell right now, so...looks like 12 days?
Comments? I have raised a dew Papilios, and the ova hatched in under 7
days.

I happened to see a female Papilio rutulus ovipositing on an ornamental cherry tree. The female happened to lay an egg on a leaf growing low enough on the tree for me to recover it. The egg was laid June 8. It hatched June 17. I reared the caterpillar indoors on Prunus serotina. The caterpillar changed colour and emptied its gut in preparation for pupation this morning: July 23.
