Leaf-mine: The mine usually starts in the lower part of the leaf and then broadens out towards the tip. The mine appears whitish on plants growing in the shade (and are very obvious as pale patches on usually the larger leaved examples of the plant), but more grey or brown in brighter habitats. The mine is lined with silk strands (British leafminers).

Larva: Details unknown.

Pupa: Within a white silk cocoon, beneath a turned down leaf edge (British leafminers).
