Hello, that looks like a Luna cocoon to me. Well since you said its warm there, it should be fine for it to hatch out now. Anyways the container should have a stick in it or something for the moth to climb up on. The container should be big enough for the moth to hatch out, climb up and expand and dry its wings, which is the most important part because they can have a wing span of 4-5 in. I would say a pop-up laundry basket would do or any thing of that nature. Oh and yes, spray or mist the cocoon with a spray bottle every other day , so the pupae in the cocoon wont dry out. also don't worry about feeding the Luna when it hatches, because it has no mouth. I hope this helped some :)

OK, I was bad and you can all beat me up verbally later. I got impatient, figuring the cocoon was no longer viable and I opened it. Well, started to open it. I breached the outer cocoon and had just started to expose the pupa when I suddenly got that sense of...weight that you mentioned before. This felt decidedly heavier than the other empty cocoon and pupa. And I stopped right there! So - here I am with a baby on my hands and I don't know what to do with it. I have rigged a cage as you can see in the pic, and the thing is presently in a room by itself with fresh air coming through the window. That's the closest I can approximate to same conditions of temperature and humidity. It will be slightly warmer than it was outside, but not by much. Without the lights on, the room is in about the same lighting conditions as the shady area it was in before. I've changed the orientation of the cocoon somewhat when I attached it to the cage - is that a problem? And what do I do next??? Will it need misting or anything since it would be getting that outside? And once the moth starts to emerge, which hopefully it's still going to - how long a process is it till it's ready to be set free? Is it more likely to do this during the day or the night? I don't want to stress it out by being caged and I don't want to miss taking a pic either. :) - Alex

Sounds like a plan. What are your plans for the book of sketches. Have you removed pupa before and had them be ok? K

Woollybear, I think the is the same photo you posted in another message. Not sure why you didn't combine those 2 messages into 1 and then had a spare message to post something else later.
