Friend? Or Foe?
Found this egg case this month (mid April 2019) while pruning/removing a dying boxwood hedge in a dappled shady area of the yard, which will be full shade once the oaks are fully leafed out. What is it? I have found other brown egg cases/cocoons online, but they don’t quite match. Thank you for any help.

Congratulations! This is the cocoon of a huge moth, either polyphemus or cecropia, in the giant silk moth family.

Quite a find.
