This pupa will eventually become a very large moth. We do not believe it is in the family Saturniidae. We suspect it is a Sphinx Moth or Hawkmoth in the family Sphingidae. Moths in this family do not spin cocoons. They produce a naked pupa like the one you found, and it is generally underground or among leaf litter. Many Sphingidae pupae are pictured on Butterfly House.
