Chrysalis on a pretty young tree in our backyard. Curious if you know if it is a moth or butterfly and what kind and if it is still viable.

Cecropia cocoon
Not a chrysalis, but a cocoon of a cecropia moth. (A chrysalis is the naked pupa of a butterfly; there is a moth pupa inside this cocoon.)
Hard to say from a photo whether or not it's viable. If you shake it gently and there's a rattle, it may still be viable... Actually, I'm not sure if that works for cecropias, but it does for some of the other giant silkmoths anyway. The moth emerges by secreting a fluid that weakens the fibers at one end of the cocoon, and pushes its way out. Doesn't look like that has happened yet. If you see tiny holes anywhere on the cocoon, they likely indicate that parasitoids have emerged and the pupa is not viable.
