The larva feeds on the young shoots of Phragmites or Glyceria maxima, often below the surface of the water. When it has finished feeding in a stem it cuts off a piece of reed about its own length and floats on this on the surface of the water until it reaches a new stem. Pupation in a stem below a prepared exit-hole.
