The monarch butterfly is a milkweed butterfly in the family Nymphalidae. Plant milkweed and stop using pesticides can help the monarch survive. The monarch was a favorite childhood sighting of mine and it saddens me that it may not be a-flutter to delight children in the future. If there was but one plant to put in my garden it would be the Buddleia, commonly called the Butterfly Bush. I spent many hours photographing an assortment of butterflies that gathered on this huge buddleia that grew beside my deck. This Monarch is one of the many shots of butterflies that came from my butterfly bush.
