Rudbeckia hirta is a larval host plant for the Silvery Checkerspot Butterfly. It is a nectar source for Monarchs and other butterflies, and a Monarch Way Station plant.

Rudbeckia hirta attracts a variety of bee species, including longhorned, leafcutter, cuckoo, bumble, sweat, green sweat, and small carpenter bees.

This plant also reportedly attracts beneficial insects to the garden, including bee wolves, soldier beetles, bee flies, jagged ambush bugs, and syrphid flies, which feed on a variety of common garden pests.
