Several days ago I saw my first large butterflies fluttering around my garden. I think there should be more.
Perhaps I am just impatient or maybe the cool spring has yet to provide temperatures high enough to bring this cold-blooded beauty into action. Or more discouraging - some of the reports suggesting that butterflies are in decline are actually true?
Regardless of the reason, the garden is a good place to encourage future butterflies. To attract butterflies you need nectar plants. Any composite or daisy type flower is a welcome landing zone for butterflies. We have already noted that butterflies are cold-blooded so pick warm sunny spots for butterfly plantings.
One of the old favorite nectar plants for butterflies and aptly named is the buddleia or butterfly bush. I wouldn't hesitate to plant them, but one must be aware that they will reseed and without a watchful eye they can be quite invasive.
To successfully continue, the butterfly needs more than food for its brief adult life. A science review tells us that the butterfly's life is divided into four stages. Briefly, the adult lays eggs. The eggs hatch into little worms that grow rapidly. The mature worm forms a pupae or cocoon that protects the butterfly as it makes the transition from worm to adult.
In our gardens it is the worm part that gets the butterfly into trouble. Every time you see a colorful worm and run for a pesticide or squash it you have just eliminated a future butterfly. Sure they can chew up some plants, but a better solution is to plant enough for you and for them.
Some of the favorite larvae foods for future butterflies are milkweeds, wild violets, the weed horse nettle, willows, most herbs, Queen Ann's lace, spicebush and carrots. A bit of research could greatly expand that list for you. In other words, you need plants for the worms near the nectar plants to facilitate the butterfly population.
Unfortunately, it gets a bit more complicated than that since each species of butterfly larvae has a rather specific plant it feeds on. You can quickly observe that in the garden or get a butterfly guide that will list this information.
My favorite butterfly reference is the one from the Audubon Society.
Another garden feature that encourages butterflies is mud. Simply place a flat rock in a muddy area. It seems that the butterfly draws minerals from the soil. As a kid I remember how the butterflies would congregate around puddles in the dirt roads.
Perhaps this one makes me sound like an ecologist, but who is better to guard nature than those of us who have discovered the joys of gardening.
