Polyphemus Moth - Antheraea polyphemus
Both moths happen to feature a character from Greek mythology in their names. Nessus was a centaur whose trickery led to the death of Heracles. Polyphemus was a cyclops from the Odyssey. There's a tradition of naming moths the larger North American Silkworm moths after figures from Greek mythology. A few sphinx moths have myth inspired name, but not consistently so. If anything, many N. American sphinx moths are named after their caterpillar's host plant.
