Yesterday my daughter and I found this strange pod under some oak trees in Prospect Park, Brooklyn, NY. It looks like some kind of cocoon–it has an imprint of a leaf on what seems like a hardened foamy surface. We’ve had a lot of storms lately so all kinds of things have been shaken lose from trees. It’s about two inches long.
Also, if it is some kind of cocoon, how should I care for it?

If it is viable, this Giant Silk Moth Cocoon will produce a gorgeous once the weather warms. Keeping it indoors with warmth due to artificial heat will cause it to eclose early and result in a sterile death without reproduction. Giant Silkmoths only live long enough to mate and lay eggs, and they have atrophied mothparts, so they can’t even eat. We believe this is either the cocoon of a Luna Moth or of a Polyphemus Moth.
Wow, that’s fantastic! I can’t wait to see what happens.
I didn’t understand from your message if I should keep it indoors or out. Right now it’s in a sheltered area with outdoor temperatures. When do they hatch?
We don’t know what the ambient temperature needs to be before eclosion will occur, but we suspect it will hatch in the spring.
Great, thanks for all your help.
I blogged about the cocoon and your answer here: http://animaltourism.com/news/2014/03/13/what-to-do-with-cocoons-falling-from-late-winter-trees
