Phytomyza myosotica Nowakowski, 1959

mine

Rather small upper-surface secondary blotch in the leaf apex, generally beginning with a short corridor that mostly is overrun by the later blotch. No feeding lines recognisable. The final part of the mine is a lower-surface corridor, mostly following a vein and containing no frass. At its end an exit slit is made; mostly the larve pupates within the mine, just before the exit.
