leaf mine - Stigmella populetorum

leaf mine - Stigmella populetorum
Cedar Rapids/ICNC, Linn County, Iowa, USA
July 20, 2010
Size: 15mm
on cottonwood leaf-I think this is in Charley's book, and that there are two possibilities , but I have to check

Moved
Moved from rosaefoliella species group.
Erik J. van Nieukerken believes, based on DNA evidence, that these two species are synonymous.

 
Update
Erik now acknowledges S. aromella is distinct, but so far it seems to be a more northern species (described from Ontario, and I reared some adults in northern VT), so I think this placement is still reasonable.

Moved
Moved from Stigmella.

Moved
Moved from Unidentified Leaf Mines. Either Stigmella populetorum or S. aromella, as described on p. 340. It's gratifying to see that you were able to use my book to reach that conclusion. I got that information from illustrations and descriptions in Wilkinson and Scoble (1979... see p. 547 for full citation). I think if there was any clear way to distinguish the mines of these two species I would have mentioned it.

 
your book
I use your book all the time now that I have it! I read it all the way through.

Moved
Moved from Frass. Let's let it sit here for a bit.

Frassed
Moved from ID Request.

 
Why Frass?
?

 
.
I remembered that in Charley Eisemans book, he mentioned two linear blotch miners that he describes as "virtually identical" and make similar mines in poplar leaves. But now that I have looked again, I noticed that they are both in the genus Stigmella, so maybe I should move this to genus level?

 
I can't help
with the ID (other than looking in his book too) but we don't have anything IDed past genus in Stigmella and we have NO MINES only adults. So if the ID is correct YES!!

 
cottonwood leaf miner
Well, there is also a moth called the cottonwood leaf miner, but I can't find pictures of its mines, or of the mines of Stigmella in cottonwood for that matter.
