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!

Cabbage Whites

The Cabbage White is our most common butterfly. They’re active throughout the summer and can be seen in just about any habitat – lawns, fields, vacant lots – with flowers in bloom. Plants in the mustard family (including cabbage) are the preferred food of Cabbage White caterpillars.
