The wingspan is 26–29 mm.
The wings are greyish, thickly striped with darker grey; the markings similar to those of the birch mocha, but the rings are nearly always reddish or purplish, and the central line is wavy.
The egg is at first bone-coloured; later, pink dots and patches appear. The caterpillar is bright green with three lines along the back, the central one edged on each side with dark green and the others wavy; the sides are blotched with pink or pale purple, or sometimes whitish and unmarked; head slightly notched on the crown, pale brown, marked with darker; fore legs tipped with pink. In another form of the green coloration, the sides are pinkish with dark-brown oblique stripes; in a third the general colour is pale brown.
The moths fly from May to August in two broods the dates depending on the location.
The larvae feed on willow.
