I agree with Owdb. leaf miner not variegation - could do with a photo of the whole tree to help i.d.

It's not leaf minor....it's varigation on a Poplar. Look it up https://www.google.com/search?q=variegated+poplar&source=lnms&tbm=isch&sa=X&ei=0MnjU_SqMaLQ7AaKpYGAAw&ved=0CAYQ_AUoAQ&biw=1280&bih=595

Nothing like the variegation on my Poplar.

Looks more like damage than anything on those Google pics I think. Are all the leaves on the tree the same or just some of them?

I will try to get more information on the rest of the tree.

Please see Badfish's latest question today folks - he has put up a much clearer photograph of a variegated leaf which convinces me - have a look.

Sorry Stera., not convinced trust that Thorpist will get back to us with a pix of the whole tree and whether all the leaves look like this.

« Cosmos - are they annuals or will they come up again next year if I leave them in...
Next question
The white looks like a severe attack of the leaf miner, rather than variegation.
