Bucculatrix gnaphaliella (Treitschke, 1833)

mine

In autumn the larve makes a thread-thin corridor with a central frass line. In spring this is continued in a much wider corridor, but soon the larva leaves the mine, and starts making fleck mines, working at the leaf underside. According to Klimesch (1937b) the larve ultimately lives as a shoot borer. Pupation in a whitish, spindle-shaped cocoon without length ribs.
