The nectar and pollen of the flowers attract a variety of insects, including long-tongued bees, short-tongued bees, Syrphid flies, bee flies, and small- to medium-sized butterflies. A specialist pollinator of asters is the bee Andrena simplex. Many insects feed on various parts of asters (leaves, flowerheads, stems, etc.), including the caterpillars of the butterflies Chlosyne nycteis (Silvery Checkerspot) and Phyciodes tharos (Pearl Crescent); other species are listed in the Moth Table (moths & butterflies) and the Insect Table (primarily aphids, leaf beetles, & plant bugs). The Ruffed Grouse and Wild Turkey feed on the leaves, flowerheads, and seeds of asters (especially those species occurring in woodlands and savannas). Mammals feeding on asters include the White-Tailed Deer (foliage), Cottontail Rabbit (foliage), and White-Footed Mouse (seeds). Asters help to provide cover for wildlife.
