Mystery of the Alien-Pod
A couple of weeks ago, Seán found a mysterious, silvery pod on the ground beside the house, about the size of a lime. It appeared to have been there for a while, as it was very light and seemed dried out. We took our guesses: was it a plant-pod? Some kind of egg sac? I thought it might be an owl-pellet, due to it's hairy outside texture, shape and size. We decided to lovingly refer to it as the “alien pod”:
There was only one thing to do in order to solve the mystery – cut it open:
Now, remember... I thought this thing was an owl-pellet...
My reaction upon opening it up:
“It... really... IS an alien-pod!”
We carefully tipped out the mummified contents of the double-layered cocoon:

The shrivelled head
Whelp, it turns out that it's actually not quite an alien, but an old pupa of a type of giant silkmoth! It seems to be either a Columbia silkmoth (Hyalophora columbia) or a Glover's silkmoth (Hyalophora gloveri), and it may have been parasitized.
You can investigate the thread I started on BugGuide which led to the probable answer here!
But for now, it shall continue to reside in its original container:
