What Came Out of This??
We found this sack, nest, cocoon attached to the underside of a palm branch at the widest point near the tree. I can’t seem to find anything similar. It was open on one side. It’s about 4 inches in diameter, an inch deep. It feels like a softer durable cotton with some fuzz around the edges.
Pima County Arizona
I am unable to determine. I would contact the local Extension program for help.
