Spilosoma spp. and Hyphantria cunea can be difficult to separate on sight. On Block Island, S. virginica is easily distinguished from similar species by the extensive orange and black markings laterally on the abdomen. If the abdomen is not visible, S. virginica can generally be recognized by the markings on the forewings: this species usually has a single black dot at the end of the cell and rarely has a few well-marked dots elsewhere on the wing.
