Slightly elliptical in shape, 0.8 mm in length and pale yellow. Eggs singly on buds, pedicels, and flowers during the first generation, and on grape berries during the second generation.

Up to 10–12 mm. Body colour ranges from brown to yellow and green. Head, prothoracic plate and legs are dark brown to black. Pinacula are large, conspicuous and dark brown. The anal shield is pale brown.
Bionomics
The larva feeds in the berries on the host plant, spinning two or three together. When full-fed it constructs a leaf-case amongst detritus on the ground or attached to a stem, overwintering therein. Pupation in that leaf-case as a second generation pupa.
The moths are active in the evening and later come to light.
Flight periods
The adults have been observed from late April till mid-September.
