not sure what this is--it may be a mine, but it is probably pretty old/empty/etc. I am sending just in case.

I think there is a viable pupa inside.

 
Adult emerged
...so if you can confirm that this was Carex flaccosperma (or something else), that would be great.

This one may be difficult--I can't find the plant anymore, suggesting to me that its season is over (I am pretty sure I knew where I found it before, and today I can find nothing like it in the vicinity). I will look for it next summer... According to Eric Ungberg, this is in the Laxiflorae group (not C. flaccosperma), possibly C. blanda, but it could be something else. I won't be able to tell without Perigynia.

 
Cool! I will try to get IDs
Cool! I will try to get IDs for these...

 
D1824
Two Cosmopterix adults have emerged from D1824, which I take it you are confident is Carex flaccosperma.

Actually, I cannot completely rule out C. glaucodea and C. pigra--these are both much less common than C. flaccosperma in this area. I'd need to take a better look at the reproductive structures to be sure, but I will try to do that. Due to the common species here, it is most likely C. flaccosperma. I am fairly confident it is one of these three.

Sad that I will not be able to confirm the species involved until next spring/summer--the reproductive structures left from this season were all too old to give an accurate ID. I will revisit this next spring/summer. Great news about the Cosmopterix.

 
D1858
I also got a Cosmopterix from D1858.
