[3] The underwings have a strong yellow band and in flight, the moth buzzes, appearing like a bee.

The forewings are violet grey when fresh and have a "barklike pattern of swirling black lines" according to David Beadle and Seabrooke Leckie.

[3] Early instars are a pale greenish white, with at first a horn, but later a brown knob near the hind end.

Final instars (75 mm in length) come in two patterns: one has brown bands such that there are ten large pale green spots on the back and an eyespot on the rear.

[3] In the final instar the knob looks a lot like a vertebrate eye, down to the white reflection spot.
