Beautiful!
That’s the way to do it and to help save butterflies.
My granddaughter was given a Butterfly Kit with 5 cocoons to watch morph into Painted Ladies. One didn’t open, while 4 did, with three being able to fly away. The fourth died because its wings were too damaged for it to fly.
We have a Buddleia Buttefly bush in our yard, plus another dozen types of flowers, roses, Rose of Sharons, Hydrangeas and 8 fantastic/nice smelling Milkweed plants for the Monards.
It’s gonna be a beautiful summer.
