mines in detail
Vitis vulpina, USA: mine in a shadow leaf; from van Nieukerken ao (2012a)
The egg is inserted in the underside of the leaf, usually close to a vein. Here begins a short, not widening corridor the usually follows the vein for some distance. Soon it turns away from the vein and abruptly widens into a full depth blotch, usually hardly one square cm in size. Eventually an oval excision is made of 3.2-4 mm in length. In the corridor the blackish brown frass generally forms a broad central line; in the blotch most of it is concentrated in the oldest part, often, especially in thin (shadow) leaves, in concentric arcs.
Two generations; hibernation als mature larva in the case, attached to the plant.
