It is a Giant swallowtail chrysalis for sure. I would know you should wait for someone like KC or Misssherry who raises them to respond

It may be an empty. You'll find out when you grab it.

Cut the two strands of silk that form the hoop around the middle. Then "grab it" and SLOWLY pull the attached end off the tree. There is a pad of silk attached to the tree and the chrysalis is attached to that pad. You are trying to get the pad to disengage for the tree. Then lay the chrysalis in some type of enclosure that provides sides that the emerging butterfly can crawl up. The chrysalis should be laying on something that the emerging butterfly can grab, like a paper towel.

I took it down but it has 2 holes on it and I'm afraid to open it.does that mean it's empty

Yes, the caterpillar was parasitized, im sorry.

Boo.

I took 6 down today. Was wondering how you were doing.

OK thank you
