larva

Chenopodium album, Nieuwendam, 28.vii.2003. The mine at left still shows something of the initial zigzag corridor. The larva at left has died before it was able to make a blotch; it looks like to corridor it made became so quickly filled with callus that it perished because of space to move.
mine
Oviposition at the underside of the leaf. The mine begins as a short zigzagging corridor, that very soon becomes overrun by a large, perfectly transparent blotch. Frass in a big black central lump. In fresh mines something like primary feeding lines is recognisable, normally seen only in Diptera mines. Pupation external, exit a rather untidy hole.
