mine

The mine begins as an inconspicuous lower surface epidermal corridor, beginning at an iridescent egg shell. This corridor is followed, and mostly replaced, by a relatively small, lower-surface, tentiform mine with many weak folds. When the mine happens to lie close to the leaf margin the leaf may fold downwards over the mine. Pupa in the mine, dark brownish black, in a loosely spun cocoon. Frass heaped in a corner of the mine.
