Green ash bugs?

Asked June 17, 2020, 8:04 PM EDT

I don't know if a bug has laid eggs on these leaves or what. Can you tell what this is and how I should treat it? I think the tree is a green Ash. Thank you, Ron

Hello. These are not eggs but a gall caused by a mite. It will not hurt the health of the tree although aesthetically it is a bit startling. It is not the emerald ash borer.

Ok, thank you so much Marcia!
