Purple Coneflowers are one of our beloved species of meadow flowers in Cambridge. A common garden plant, coneflowers are found at Fresh Pond Reservation and elsewhere—including in the Honk! parade.
These flowers are cross-pollinated by long-tongued bees, bee flies, Halictid bees, butterflies, and skippers. Among long-tongued bees, are such visitors as honeybees, bumblebees, digger bees (Melissodes spp.), and leaf-cutting bees (Megachile spp.). Butterfly visitors include Monarchs, Fritillaries, Painted Ladies, Swallowtails, Sulfurs, and Whites. The caterpillars of the butterfly Chlosyne nycteis (Silvery Checkerspot) feed on the foliage, while the caterpillars of several moths feed on the flowerheads. These latter species include Chlorochlamys chloroleucaria (Blackberry Looper), Eupithecia miserulata (Common Eupithecia), Synchlora aerata (Wavy-Lined Emerald), and Homoeosoma electella (Sunflower Moth). A small songbird, the Eastern Goldfinch, occasionally eats the seeds during the summer and early fall.

Milkweed is an important host plant as well, with a specific relationship with Monarch caterpillars eating only milkweed species. Check out the red milkweed beetles on this plant, next time you are in a meadow!
