Felt-like eriophyid mite erineum patches are now very obvious on American beech (Fagus grandifolia) in southwest Ohio. I've long identified the culprit behind the patches as Acalitus fagerinea (family Eriophyidae). However, I'm now convinced there may be two species of eriophyids that produce erineum patches on American beech.
