We got this neat kit here. The whole life cycle was about 2.5 weeks.
You leave them in the jar until they change into a chrysalis.
Then you carefully remove them and tape the paper to the top of the net.
I am week or so you will have butterflies!
Releasing them outside so they could start the life-cycle again.
Very pretty and they loved my Iris.
After the butterflies drank from the flowers, about 10 mins, they flew off to other places 🙂
