Saving the Monarchs
Monarch butterflies are one of the most easily recognized and beloved butterflies we see. Everyone knows the bright orange and black markings of the monarch. It's hard to imagine a world without them-- but it could happen. Monarchs, like all butterflies, are threatened by the loss of habitat that happens when development turns meadows and fields into condos and shopping malls. Host plants are mowed down, and pesticides and herbicides are lethal. Monarchs are in particular danger because the plants they depend on, milkweed, are disappearing in the wild.
What can one person do to help?! Last year my mate4life and I planted a new flower bed, a butterfly garden. I did some research and came up with a list of plants that are good sources of nectar. Word must have spread, because we had many beautiful butterfly visitors to the flower beds. The photo above shows a monarch on one of my lantanas, taken last Sept.
This year, I am taking the butterfly bed a step further --planting host plants, where monarchs and perhaps other species can lay their eggs. Milkweed plants support the emerging lavae and adult monarchs.
There is an organization called Monarch Watch that helps people start butterfly gardens and certifies back yard butterfly gardens as Monarch Waystations: http://www.monarchwatch.org I'm preparing our back yard garden to meet the requirements of a Waystation.
Nectar plants in our flower beds:
Lantana (planted as annuals every year, not hardy in Indiana.)
Rudbeckia (perennial variety)
Galliardia (Blanket flower)
Echinacea (purple coneflower)
Zinnias (important to include single flowers like Pinwheel Zinnias--bees need them, and hummingbirds like them!)
Catmint (purple flowers, looks like salvia)
Joe Pye Weed (native species, very good nectar plant--and besides, I love the name!)
Milkweed host plants: so far, 3 swamp milkweed plants (Asclepias incarnata) and 2 butterfly weed (Asclepias tuberosa). Monarch Watch says 10 plants or more is ideal, so this weekend's task is to add some more plants. You can do this more cheaply with seeds, but it is not so easy, and I think my chances of success are very low.
So far this spring, we've had Tiger Swallowtails, an American Lady, a yellow sulphur, and a small blue butterfly that was too quick for me to identify. We'll keep watching, and planting, for more butterflies.
