The empty shells are flat and shining and are conspicuous, usually seen with a magnifying glass.



Pay close attention to abandoned mines, because they resemble the mines of a Diptera Agromyza albitarsis very well. Also look out for the Hymenoptera: Heterarthrus ochropoda (sawfly) which occur at the same time on the host plant, if no caterpillars are present in the leaf mine.

The usually 5 to 10 eggs are deposited in groups on the upperside of the leaf, usually along a vein. The white larvae form large, upper-surface blotches in which many larvae may be present because mines can merge.
Pupation is external, mostly on the leaf. Exit slit in upper epidermis.
