Walnut blister mite  - Aceria erinea

Walnut blister mite - Aceria erinea
Medford, Jackson County, Oregon, USA
May 22, 2009
These are pictures of leaf galls on my English walnut tree produced by feeding damage from the walnut blister mite. The mites cause raised yellowish-green blisters on the upper leaf surfaces. On the underside of the leaf is a yellowish felt-like mass or blister where the mites can be found. These mites cause no appreciable harm to the tree, and do not inhibit the development of nuts or fruits, so no control measures are necessary (the leaves just look bad).

A new guide page can be created for this species of mite.
