mine

The mine begins with a densely wound spiral corridor in the sponge parenchyma of the leaf underside. Then the corridor becomes upper-surface, starting at the spiral spot, that by now is quite transparant. The upper-surface corridor is rather straight-walled, and follows the leaf margin over long distances. Frass in pearl chains, towards the end of the mine in isolated, coarse grains. Pupation outside the mine, exit slit now upper-, then lower-surface.
