Christmas Mystery Cocoon

In honor of Christmas and the season of giving I bring you this mystery stocking stuffer, encountered in Argentina.

First, the present all wrapped up and hung on the tree.

Peeking inside...

Removing the first layer of wrapping...

The mystery present all unwrapped.

Ta-dah!  Your present seems to be some kind of hymenopteran pupae.  And if you can tell me what they are, that will be my present.

…merry Christmas and happy holidays, y’all!
