Hatching butterflies

We got a kit to hatch these butterflies like you see in the picture.  

It comes in a bunch of small containers that have painted lady caterpillars and their food.

Eventually they turned into a chrysalis.  We took them out of the container.  They were attached to a small piece of paper like you can see in the picture.  We taped the papers with the chrysalis attached with tape to the top of the butterfly house.

After almost a week they turned into butterflies.  When they are almost ready they get very clear and have spikes on the outside of their chrysalis.
