Ash Spider Mite
The ash spider mite (Tetranychus homorus) can produce a peculiar sight on ash trees in the fall of the year (mid-September). The trunks of ash trees may be covered with silver webbing giving the appearance that the trees have been “wrapped with cellophane.” Under some circumstances, the webbing is so pronounced on the majority of the trees that it appears that they are shrouded in a fog.
