Mine of Pegomya nigrisquama Image: Rob Edmunds (British leafminers)

Leaf-mine: The pale-coloured mine runs on the upper side irregularly to the sides, in the middle with blackish spots, where the frass is deposited. It starts in the center of a leaf and without a small mine leading to a large mine. Many mines in a leaf could finally cover the whole leaf (British leafminers).

Larva: Details unknown.

Puparium: Details unknown.
