Length 6 to 7 mm. Leafhoppers in the Idiocerinae are large and often highly patterned, with a very broad, short vertex. The group is large and often very difficult to identify. In I. herrichi the facial markings, banded costal margin, broad pale midline to the pronotum and markings on the scutellum (three dark triangles with a horseshoe-shaped mark) are diagnostic.
On willows (Salix alba and S. fragilis), and may overwinter on evergreens.
Adult: August to September sometimes later
A previously scarce species found only in southern England, it now appears to be well established and spreading its range.
