Slug eating cherry leaves! What is it?
Could you please tell us what type of tree this is? That information will help us assign the question to the correct person. Thank you!
I think it is a weeping cherry.
Yes it is a cherry. I can tell by the glands at the base of the leave.
This pest is the pear sawfly, Caliora cerasi, often called pear slug. It is a pest of cherries, plums and pears. It is easy to kill with an insecticide. The leave feeding is the damage it does. There is a second generation later in the year and you may want to treat then.
