Could be shot hole disease.

Here is a link that might be useful: Coryneum Blight

When do your leaf cutter bees become busy cutting out holes in leaves? I have some very interesting looking plants in my yard too.

The leaf cutter bees are busy here, too. The other day, a nice calm day, I saw what appeared to be a yellow flower petal flying around. Looked closer at the Thunbergia (where the petal started 'flying') and discovered much damage from the leaf cutter bees, and the bee was actually flying away with a piece of the petal. My Skinner's Bronze Mayday (very similar to Shubert Chokecherry) looks much the same as yours, Konrad.

If the damage occurred in early spring, especially with chokecherries and their very early leaf out, it's doubtful that it was leaf cutter bees that caused the initial damage.

They seem to be very active this year, whatever the case.

Thank you all!

I have been looking for bugs or anything what could have done it but never see anything!
The leafs came out of their buds in spring already deformed.

Shot hole disease makes the most sense so far....thanks!
Have you had this on your trees?

Konrad

No, but from what I've read, by the time you notice the holes in the leaves, the fungus has come and gone. It isn't supposed to be very damaging to the tree, however. According to that link, dormant oil spray should help.
