Wildlife value

Heart-leaved aster flowerheads attract many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, and beetles. Many insects feed on the foliage, including leaf beetles, the larvae of leaf-mining flies and fruit flies, plant bugs, stink bugs, lace bugs, aphids, leafhoppers, and the caterpillars of several butterfly and moth species. Other wildlife use asters to a limited degree. Ruffed grouse, wild turkey, and tree sparrows eat the leaves and/or seeds, as do mammals like chipmunks, white-footed mice and white-tailed deer.
