Asclepias tuberosaThis is the native milkweed that the Monarch butterflies use as a food source in both the larval and adult stages, though in the larval stage it consumes the leaves, and in the adult phase it consumes only the nectar, but may leave behind little eggs that hatch into caterpillars.

The nursery trade typically only has Asclepias curassavica, commonly known as Tropical milkweed, which can be distinguished from tuberosa by the colors of its flowers, which include both red and orange.Monarch butterfly

I was at a local demonstration garden near where I live, and observed a large number of plants that were definitely yellow, along with a few that were the red and orange  A. curassavica species. They even had a few Monarchs visiting, although the southbound butterflies have been few and far between so far this season.

Larva – Danaus plexippus (Monarch)

This past Friday, October 3, 2014, I found four Monarch larvae on the milkweeds in my front yard. In the cool of Saturday morning, I located one still on the milkweeds and one on a nearby rock, slowly moving towards some groundcover under the oak tree. Later that afternoon, someone came by who has been actively nurturing the caterpillars, and we found just one, on a milkweed, that was transplanted to their yard a few miles north.

And so it goes. Imagine how many more Monarchs would be around if large chemical companies had to include some sort of environmental impact statement in their marketing, such as :

For a Few Dollars More – improves crop yield by selectively killing native plants that are essential to the survival of certain insect species, including the Monarch Butterfly (Danaus plexippus).

Extinction Is Forever – The life of an insect may span less than a year, but the extinction of a species may echo through the years. Who knows what pests you may unleash by using a pesticide to upset the natural balance of your local ecosystems? Who cares as long as we get a positive growth in this year’s balance on the bottom line? Let the next generation of scientists and economists figure out the true costs of our actions today.

“And so it goes.”  (I think Kurt Vonnegutt said that fisrt.)
