Importance to wildlife:
Similar species (if any): Galinsoga parviflora (Small-flowered Galinsoga) is similar. G. quadriradiata is more hairy and has larger ray florets (0.9 - 2.5 × 0.9 - 2 mm versus 0.5 - 1.8 × 0.7 - 1.5 mm) than G. parviflora. There are very few reports of G. parviflora in Wisconsin, with available observations from the southern part of the state.
