Polydamas Swallowtail - Battus polydamas

Polydamas Swallowtail - Battus polydamas
South, Florida, USA
Battus polydamas pupae take on two different color forms determined by surroundings, not sex. If the larva pupates on a smooth surface, it will usually produce a green pupa as it equates smooth with new growth. If the surface is rough, it equates that as mature growth and that normally produces the brown variation.

Nice, Alan!
A demostrative and beautiful photo. We currently have a very large brood pupating in our back yard right now. They've all but stripped their host plant!

 
Chrysalis
How far do they go from the host plant to make their chysalis? Have you observed that?
