Large, white, primary, full depth blotch, following upon a very short gallery. The mine begins close to the leaf margin, expanding deeper into the leaf. Frass in striking, long threads. Pupation in the soil. Vacated mines shrivel and wither away; later in summer not even a trace remains.

Only the larva enables a certain identification.


Betulaceae, monophagous

Betula pendula, pubewscens.


Mines in late-March till May (Heath, 1983a).
