Above you can see the stages in their folders during over a month of observations. Also, Big Sister was trying to color a newly transformed beetle. She had the real beetle next to her picture to give her a color reference. Looking at this picture, I understand why they thought it was a lighting bug.
Here is an update regarding the caterpillars. They had all transformed into chrysalis. We moved them to the butterfly environment as we patiently waited for their own metamorphosis to take place. Then they started to emerge as beautiful painted lady butterflies.
Above, the kids were drawing the butterflies. If you look at the blackboard by the wall, you will see a record of all the changes comparing both types of insects.
