This was a toughie teaser.

It a Cecropia Moth cocoon.

We would not have known what it was without consulting a nationally recognized moth expert, who writes:  "The Cecropia is by far our largest silk moth and a real beauty, too!"

Congrats to Mike Gempp, who said it was a Silk Moth cocoon.

We'll have some exciting moth news in coming days, so stay tuned!
