The overall coloring of the imago, or adult, elm sphinx is a gray-brown with wavy markings covering the forewings.
In the upper center of the forewings, as with other Ceratomia species, there is a small white dot.
The hindwings are a plain gray with a darker band running the length of the near-edge.
The outer ends of the forewings and hindwings are both dashed with a light-dark-light pattern.
Three broken, dark bands run the length of the body from the thorax to the tip of the abdomen.
The antennae are stiff and wiry and have hook at the tips.
Some specimens have a prominent splash of bright white on their upper head and wings and stand out considerably from other C. amyntor.
