Oviposition on a young shoot. The larva leaves the egg without filling it with frass, and the empty shell soon drops off. The first section of the is a shallow, sinuous gallery running upwards between the ridges of the shoot. Later the gallery becomes deeper, sometimes changes direction, and is no longer influenced by the ridges.
The mine strongly resembles the one of Trifurcula immundella. However, in that species the egg is filled with frass when it is left by the larva, and remains as a black, shiny semi-globule at the start of the gallery, even after the mine has already been vacated. Moreover, generally the gallery of immundella runs downwards (Emmet).
