Caption: This is a cocoon or chrysalis of some type - I don't know my cocoons very well. Could this be a praying mantis cocoon?

Thank you, Kathy. I will keep an eye on it but
am sure I will miss its emergence as is on
another street over from me. I don't dare
disturb nature by bringing it home.

This is the cocoon of a large silk moth, perhaps a Luna moth or a Cecropia. If it feels heavy and rattles when shaken as if there were a pebble in it, it is alive and the moth will emerge in spring. If it's lightweight, either the moth has already emerged or else some parasite or predator has already killed the pupa.
