Moved

Moved from Unidentified Leaf Mines.

I guess my previous comment was based on the assumption that this was something that has been reared from Carex before. I did notice that the frass pattern was unusual, but the larva appeared to be a lep from what I could see. Taphrocerus species are mostly associated with Cyperaceae, but this is the first time anyone has found a larva on Carex. I'll get the adult identified eventually... do you think this was more C. flaccosperma?

Exciting news--I can't think

Exciting news--I can't think of anything else it would be. If not a Carex, then a Cyperus (not that) or Scleria (not that). I am pretty sure it was Carex, and C. flaccosperma seems most likely, given that Carex with similar glaucus leaves from the same section of woods turned out to be C. flaccosperma (and I saw no other plants like it in the same area).

Gelechioidea

Elachista or possibly Cosmopterix. I hope this larva hurries up; it is almost out of leaf. I'll add a fresh sedge leaf in case it is able to make a second mine.
