Ophraella
I looked around and am sure it is an Ophraella spp. but not the species in the guide.

My pictures are kinda crappy but it looks exactly like:


Now if I can just get the darn thing to species. My best guess (using Downie & Arnett) is Ophraella communa, a species said to be found on ragweed. Could be it, but I'm not sure. Can anyone verify?

 
More info
This website has a story on O. communa being invasive in Japan. Their picture matches well.

I'm pretty sure this is a + id. Looks like we need a new guide page.

 
O.communa
could be it....the picture of this specimen is darker though and on the other one the black stripe seems broader. I can´t see the same black stripe patterns from O.communa on your photo´s, maybe you can on the actual specimen. The margins of the elytra don´t seem like Galerucella, but with these pictures I can´t even rule out that for sure. Would it be possible to take a new photo with more light and some sharper???

 
The darker color is from it n
The darker color is from it not being a good picture. I'll try and take another but its definitely the same elytral pattern as the thumbnail I have in the thread above. These two images of mine should probably be "frassed".
In any case, the other picture (not mine) is surely O. communa and should probably be moved as such. It seems that the elytral pattern is the important distinguishing factor between species in this genus.

 
Ophraella communa
Ok, thanks for the comment. I agree on the other picture being Ophraella communa. I´d be nice too if you could take a new picture with better light so we would have two pictures for this species in the guide.

Chrysomelidae: Galerucella sp.
I think it is a Galerucella.
