Aculops tetanothrix, commonly known as the willow gall mite, is an eriophyid mite species that induces gall formation on Salix (willow) species. The mite has been documented in parts of Europe including Belgium and Denmark. It is characterized by yellow body coloration with brown or sometimes orange markings. The galls it produces on willow foliage initially appear green and later develop red coloration.
