Digitivalva perlepidella (Stainton, 1849)

spikenard fanner

mine

One or several broad corridors, radiation from the leaf base, often along the midrib, towards the leaf tip widening into a roundish blotch, not containing any frass. The larva, that seems to feed only at night, retreats during feeding pauses in the leaf base and is invisible then. Often two larvae in a mine. Pupation in a little separate mine (pupal chamber). Mines mainly in the lower leaves.

In older literature often associated with Plantago major; this goes back to confusion with an Apteropeda mine (Hering, 1963a).
