As a further part of this topic, the boys have been able to observe the complete metamorphosis of caterpillars into butterflies. The four different stages of the life cycle (egg. lava, pupa and adult) have been fascinating to watch, especially the rapid growth of the caterpillars and their transformation into the pupa stage. After the adult butterflies emerged, dried their wings and fed on fresh oranges for a few days, the boys thoroughly enjoyed releasing the painted ladies into the playground, ready for the life cycle to start all over again!
