Gall wasp 2 - Druon quercuslanigerum

Gall wasp 2 - Druon quercuslanigerum
Russ Pitman Park, Houston, Harris County, Texas, USA
Size: larva ~2.5 mm
I think the gall was found on 11/29/09, but I'm not sure. I just now opened the gall and found the larva inside. Will it die now that it's been exposed, or will I get to see it pupate?

This "capsule" was disc-like in shape, but it was found with ones that were more elongated.

This photo taken 1/31/2010.

Adult
The larva in this image is now an adult, and I've added the images. (Thanks again, G Whiz--I just kept it on a paper towel in a container and moistened it every two or three days, and it did great!) I've also re-done the linkages and remarks. (The adult I'm talking about here is the one in the linked images. It's not the one referred to in earlier comments.)

Moved
Moved from Gall Wasps. This seems to be a pretty good fit. The old photos I've seen don't show the details very well, but the descriptions (forthcoming on the guide page) seem to match.

 
Thanks, Charley
Glad to have a probable ID!

We have an adult now
new photos added

 
Nice!
Are you keeping the specimen? Texas/SW galls are so poorly known, there's a good chance you're documenting something new here.

 
I still have it
I was considering releasing it but I'm definitely willing to keep it as a specimen, or send it to someone. I know nothing about preservation.

 
Up to you
I have no idea who would be qualified and/or willing to identify cynipid specimens at this point. In the near future I'm planning on getting more serious about rearing gallmakers, leafminers, etc. and keeping the specimens, so eventually I should have a way of getting definite IDs. Since we have a proposed ID for this one now, it's possible to check the specimen against the original description for this species.

Moved from ID Request.

Host plant
Do you know what species of oak this is (assuming it's oak)?

 
Don't know
I was hoping someone here might know, lol.

 
Southern Live Oak?
Perhaps someone with better knowledge of east-Texas trees can chime in, but this looks like it could be Southern Live Oak (Quercus virginiana): unlobed, revolute margin; rounded tip.

No expert, but . . .
if I had one of these, I'd cover the open side loosely with soft (bendable) paper and put the whole thing in a jar with paper toweling that could be misted once in a while to restore the moisture lost by opening the gall.

 
Good idea
Thanks!
