I was told it is a Cecropia Moth (Hyalophora cecropia) cocoon. After doing an internet search, it looks right to me. I hope so.

Recreating a native habitat has been a dream of mine since I was about 18. It only took me 20 years, but I finally have two acres of land in the country with which to work (and play). My goal is to document the improvements I make to the property: restoring habitat & attracting birds and butterflies in addition to other wildlife.
