The southern phases are more orange yellow colored, brighter, and more pale.

All phases have a "7" mark on their wings with the eyespots, lavender patches, and buff-patterned borders.

These moths are diurnal and their mating period is in the afternoon.

Their lifespan is about two weeks, long enough to mate and lay eggs.

Like other moths in the genus Callosamia, the caterpillar spins a hanging cocoon that has leaves attached to it.
