Phyllis Wezeman's curriculum, "From Caterpillar to Cocoon to Butterfly" can be found at: https://www.leaderresources.org/Caterpillar-e-book OR https://www.leaderresources.org/CaterpillarBook
It is curriculum that you download from this site for a cost.
The project is wonderful and well worth the price.
Thank you for the info, Phyllis!
