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 :)

Yes to the Sassafras... Variability in host-plant quality for the larvae of a polyphagous insect folivore in midseason: the impact of light on three deciduous sapling species T.L. Osier* & S.M.

Copyright © 2007 The Authors Journal compilation © 2007 The Netherlands Entomological Society KEYWORDS light availability  Acer rubrum  Prunus serotina  Sassafras albidum  Callosamia promethea  Lepidoptera  Saturniidae Abstract We examined the effects of light availability on the suitability of foliage from red maple (Acer rubrum L.) (Aceraceae), black cherry (Prunus serotina Ehrhart) (Rosaceae), and sassafras [Sassafras albidum (Nuttall) Nees (Lauraceae)] for the larvae of the promethea moth, Callosamia promethea Drury (Lepidoptera: Saturniidae), in midseason. We identified replicate sun- and shade-grown saplings of red maple, black cherry, and sassafras from naturally growing populations in the field. Foliage collected from the experimental saplings was bioassayed using early instars of the promethea moth and assayed for nitrogen and carbon content. Promethea moth-larval performance and survivorship was highest on sassafras, intermediate on black cherry, and lowest on red maple. Larvae feeding on foliage from plants grown in the sun performed better than from those grown in the shade; the effect of light did not depend on sapling species. Foliar nitrogen content varied among the sapling species and was higher, overall, in foliage from plants grown in the sun. Nitrogen concentration related strongly and positively with larval performance and accounted for a great deal of the variation in performance both among the sapling species and between the sun and shade treatments. During midseason, foliar nitrogen content is determined by light availability, it varies among sapling species, and it is likely the primary constituent determining host quality for folivores on these sapling species.

Is this the same pupa from the other post? Interesting how you can see it developing. What are you using to post photos?I can help you with posting multiple photos in a single message. That would make these snippets you post more valuable.

Woollybear, if you are limited to 2 posts... You can post multiple photos in one post. Did you open this or did it hatch on it's own?
