My ornamental, cherry trees are losing leaves on lower branches. Upon investigation I found these strange curled bugs on the leaf. Could you tell me what they are and how they are to be treated. Thank you

Expert Response
Those are not insects/bugs but an interesting part of the normal anatomy of a cherry tree.
They are glands called Extrafloral Nectaries.
Here is a page from Ohio State University with some information about them:

How does the tree look overall?
This late in the season trees can drop some excess leaves and it's not a problem. If you have other questions or concerns, let us know.
