Once, only once, have I been able to watch a chrysalis transform into a butterfly. Such a fascinating mystery to watch. We put it in a jar. One day we found a Monarch butterfly fluttering around the jar anxious to get out! It happily flew away.
One of our gardens is a designated pollinator garden. That means I allow the milk weed and other insect loving natural plants to grow as food for the Monarchs butterflies and other native insects. It is growing larger every year. I have even mailed milk weed seeds to folks interested in having beneficial pollinating plants for nature in their gardens.
In addition, I have great fun taking photographs of butterflies. Though often it is a real challenge!
