Milkweed Update

Our Common Milkweed plants are now bending under the weight of rapidly maturing seed pods. The butterflies and moths are gone, but their eggs have hatched and the next generations are foraging aggressively on milkweed leaves.

Confession: I was unfamiliar with this creature until recently and my first photos were butt shots. Didn’t realize I shot the wrong end of the caterpillar until it started moving!

Milkweed: plant it and they will come!

In recent years milkweed has received much attention as habitat for dwindling populations of monarch butterflies. Most of the more than 100 species in the Americas are tropical, but one species in particular is a staple of monarchs in the North: Common Milkweed (Asclepias syriaca).

My backyard milkweed project started in 2015 with a few transplants from a nonproductive, roadside location. Establishment was slow, but they’re now flourishing. Vegetative reproduction by root sprouts has created a colony of about 30 stems and the large, fragrant flower clusters are insect magnets (according to the US Forest Service, over 450 insects are known to feed on some part of the plant, including flower nectar). I focused on the Lepidoptera, attempting to document the variety of butterflies and moths that benefit from flowering milkweed. Multiple benefits from a single management action is a best-case scenario. The value added from a colony of milkweed is much greater than monarch habitat.

I’ve observed 9 or 10 species of butterflies and moths thus far, as well as countless bees, flies and other insects. This is a sample!

Monarch Habitat: Milkweed

A fringe benefit of autumn leaf peeping is the discovery of other natural phenomena and photo opportunities. When setting up for the landscape scene in my last post, I couldn’t help but notice the white gobs of milkweed seeds along the untidy fencerow in front of me. Prime Monarch butterfly habitat! Still attached to the opened pods, the tethered masses of seeds were waving and fluttering like flags in the stiff breeze.
