"holes" in siberian elm leaves #653008

Asked June 18, 2020, 8:33 PM EDT

A friend tells me that I have Siberian elms (because of small leaves) in my backyard. I just bought the place and, with Spring, the leaves came out and they are lacy, where you can see through the leaves in a shotgun pattern on all of the leaves. Is it an elm beetle? And can I control it without chemicals? How dangerous is it for the tree?

Expert Response

The holes in the elm leaves were likely made by some type of insect, possibly the elm leaf beetle.  The damage to the tree is minor.  Control treatments are not necessary.
