Early Birch Leaf Edgeminer - Fenusella nana - Female
Seattle, King County, Washington, USA
May 5, 2007
Size: 7mm
I believe this to be the same as
It seemed to be ovipositing on my Paper Birch, Betula papyrifera.
I'd like a guide page for this little lady. It's a very common and disfiguring insect to many birch species. It doesn't really hurt the trees, but is very, very "ugly" to have many leaves of your tree turning brown and papery.

promised, I´ll not do again!
Risky procedure, to move images according to a present ID - in a group one is not familiar with at all. I guess, I was tempted here because of the clear host plant association . . .

Well...
I watched this one pressing her abdomen to the edges of the Birch leaves, that was how I was able to get so close. She was busy doing whatever she was doing. If mine is not this species, I have no idea where to go. The first photo I took of what I believe to be this species has black eyes and this one has golden eyes. I don't know what that means, either.
