Coordinator notes: According to Wagner and Giles in "Caterpillars of Eastern Forests" The red-humped oakworm (<i>S. canicosta</i>) is similar to white-headed prominent (<i>S. albifrons</i>), in which black and white dorsal stripes are more similar in width; whereas in <i>S. canicosta</i> the black stripes are wider than white. This is easier to see when the caterpillars are side by side.
