Wildlife notes

For Sky Blue Aster, the nectar and pollen of the flowerheads attract bumblebees, digger bees, leaf-cutting bees, Halictid bees, Andrenid bees, Syrphid flies, bee flies, butterflies, skippers, miscellaneous beetles, and other insects. In addition, larvae of the butterflies Silvery Checkerspot and Pearl Crescent feed on asters, as do larvae of the Aster Borer Moth, The Asteroid, and many other moths. Among birds, the Ruffed Grouse and Wild Turkey browse on the leaves and seeds of asters; the Tree Sparrow also eats the seeds during the winter. Among mammals, the Cottontail Rabbit and White-Tailed Deer browse on the foliage, while the White-footed Mouse eats the seeds.
