What plant this is? (growing, bugs, 2015, butterfly)

Does anyone recognize this plant? Its a young tree that emerged from nowhere on my backyard, and grows very fast.
Thank you!!

No one?? Need a different picture, perhaps?

[PAhippo]

maybe an over-all picture to see the shape and size of the plant?

It doesn't look familiar to me but I'm in gardening zone 5. It may not grow here.

Do all the leaves have that 'bladder' at the base? Or could those be insect galls.

No, not all. By the end of the year, when the plant lose all their leaves, the "bladders" look like a dark, dry berries, in cluster of 2-3. Definitely pretty weird looking plant right now.

Yes, I will. Although my neighbor has it growing like a tree, but in my backyard, it grows like a shrub.
I will take pictures of both this weekend.
Thank you all for the replies

Finally a mystery is solved!

What you see here are three of MANY gall psyllids (Pachypsylla - an aphid-like bug) that reside within the leaf petioles and blisters on the leaf blades.
These swollen structures appear at first to be a fruit of some kind. The bugs produce an irritating substance similar to a plant hormone that causes the petiole to swell providing both room and board for the uninvited guests. The structures become very hard and durable and remain on the tree through the winter providing the psylids a very secure home.
The gall somehow prevents the leaf from falling from the tree - ungalled leaves are shed normally.
Ladder-backed Woodpeckers (Picoides scalaris) love to consume psyllid content.
However, the flexibility of the leaf petiole makes the breaking open task difficult; the bird must secure the leaf with one of its toes to get enough leverage.
Most likely a hackberry.

How fascinating!!!

Yep, just as I thought. Insect galls. The key point is that they do not occur on all of the leaves. If you open them up you also do not see any developing seeds like a weird fruit might have. Sorry I missed your post that had the info about the lack of bladders on all leaves. But it is fascinating isn't it. Wait until you see galls on oak trees.
