Most of the spots are white, but the first two to four are red or orange. A clearly red or orange ring on the abdomen. Hindwings are dark with 1 white spot.
The Amata phegea is mimicking the Z. ephialtes. If you compare these two species you can immediately see that they are different. The Z. ephialtes is very variable, this is the yellow/white form which is very similar to A. phegea. The one hanging upside-down is the orange/red form.
The mimicry is for an obvious reason - Z. ephialtes is poisonous.
