I had a similar experience last week. I saw the caterpillars, lots of them, but could never see a chrysalis. Last week, I saw one one my hollyhock, which was at least three feet from the butterfly bush, and wondered how it got there. I was watching it for a few days when we had quite a storm one night, and it was gone the next day - probably blown/washed away. I never got around to getting a pic. but it looked exactly like yours.

Bjorn, it sounds great! What do you mean when you say "rendered stone"? Does that mean it is concrete molded to look like stone? Our barn was white wood, then in the 60s it got clad in white steel. It is still there. The paint has eroded alot, but the steel really has protected the old barn. My DH grandfather and grandmother were from Sweden. His name was Nels. He was sort of an SOB I think, but he died in the 40's. He didn't have my DH son until he was in his early 40s then my late father in law didn't have my DH until he was in his mid 30s. The generations are really stretched out. We are in our mid 60s and we have a daughter that is 26 and a son that just turned 25. Though I have a son in his mid 40s from a previous life, lol. In Iowa there were a lot of German and Swedish immigrants settling here in the mid to late 1800s I'm really off topic now hahaha

I suspect (but am too scared to test it) that it will be fine outside over Winter. It sat next to a glass window pane all Winter and didn't seem to suffer. It got to about -4 here if that helps? I know it's hardy because I accidentally watered both of them with scalding hot water and they were fine. Whoops!

Australia has a very strict quarantine on incoming plants, that's why. what, you did not know? and of course you'll have to pay for shipping ...a-ha-ha...- makes no sense whatsoever! the cutting won't survive the long process in any case. you prolly can get something similar from Thailand faster and with phyto certificate.
