Grape plume moth may start showing up in vineyards soon, though it is a sporadic insect in vineyards in the Midwest. The characteristic injury is caused by the larvae webbing together the terminal leaves on a shoot to protect themselves from predators and parasitoids while feeding on the tender leaves. Peak infestation usually occurs around the end of May into early June in southern Wisconsin. Learn more here.
