mine

Large, deep, upper-surface blotch that starts at the leaf margin, without an accumulation of frass. Around the oviposition site the leaf turns reddish brown. Frass in scattered grains, but towards the end of the larval period an opening is made in the mine, and both frass and exuvia are ejected. Against that time the mined leave is shed, and the larva makes a disk-shaped cocoon within the mine, in which it diapuases until the following spring.
