As a fifth instar, “Seven” is eating voraciously, preparing for a final molt and the chrysalis stage.
“Seven” in the “J” shape; the chrysalis stage is imminent. He will molt once more in this position.
“Seven” has completed his final molt and transformation into chrysalis form. The chrysalis hardens after a couple hours and the metamorphosis begins.
Danaus plexippus nicknamed “Seven” minutes before emerging from the transparent casing that is all that remains of the chrysalis form.

“Seven” spends the night in his enclosure because he emerged from the chrysalis too late in the day to be safely released. Next morning he flexes and extends his wings, ready for flight.
