Historical References

British entomologist Dru Drury would include an image of the species in his three-volume publication Illustrations of Natural History, Wherein are Exhibited Upwards of 240 Figures of Exotic Insects, published between 1770 and 1787. A plate from that publication is below.

Floral Associates

Hyalophora cecropia caterpillars are polyphagous and feed on a wide variety of vegetation. Adults lack a digestive system, do not eat, and exist solely for reproduction.
