Moth Larvae

Moth Larvae
Bay Center 98527 Willapa, Pacific County, Washington, USA
October 23, 2011
Size: Est 12mm length
Interesting encasement built on a limb at the junction of a another limb. Fairly hard structure. I think it a moth but not sure. I will try and grow it to metamorphous.
Grand Daughter found and will have to get exact location if important but think Pacific County ( or very close to it).

My 2 cents
for what is worth it reminded me of a fat green Polyphemus Moth cat. Not sure if they turn this color at this stage, or if cocoon/encasement situation found here fits the species.

 
I have raised what I called Antheraea polyphemus
It is much larger and .. different.

 
raised on
maple? i raised mine on alders..

i would
gently put it back in the hollow it was in then using a couple pieces of tp to hold it there like a brace place it in a tupperware type container put a drop of water in the tp, and id keep it in your garage..where it felt the effects of the winter up there..and leave it till spring. i dont know about the refer crisper thing..it hasn't shown much to me. i have much better luck in the pumphouse where i keep all my critters. it looks like a moth to me too, and sometimes they sit in that condition for months before pupation.

 
Thanks ... I have already taken care of most
of those suggestions. I did not attempt replacement yet but the larvae is in a large pill bottle with a couple of leaves (for the mositure) and resting in our unattached garage and shop at ambient temps. I was not sure of the replacement and in this case I will have to remove some of the branch fragment to place it back in without injury. This was on a pruned branch and the little twig just happened to break off and the small larvae noted. Otherwise it probably would have ended up on the burn pile.
Any idea of what moth? I have over 400 species from here and just found a new one (Lithomoia germana) last weekend that I will post before DNA results as Lars Crabo has confirmed ID.
Thanks

 
Interesting stuff!
How cool you found something new.

For whatever reason, the photos made this thing look pretty big to me; I had pictures the wood structure as a "branch" rather than a "twig"!

 
well those leaves will mold is the only thing..
where the tp doesnt..you can just wrap it in a fold of tp, for that matter..best of luck with the little fella, i'm subscribed and not a clue as to who. house is about done im in it, its warm and next mothing season i will try and catch you in numbers..i pretty much lost 2 mothing years.. dag nabbit!

I'm no expert on such things,
but I'm pretty sure that's a beetle larva. It'll be neat to find out what it turns into, but you may have to provide it with the right food source if it isn't about to metamorphose.

 
Looks like a moth prepupa to me...
and if I understand correctly, it was removed from its cocoon, in which case it won't be feeding anymore. It presumably will overwinter before metamorphosing into an adult. It may be possible to keep it alive until then--keeping it in the fridge is probably the best bet--but it would have been better off left in its cocoon.

 
Oh
I forgot about that particular stage - you're probably right!
