puparium, made transparant
gall
The larva begins its life between the youngest leaves but soon its bores itself down through the growing point and thence feeds on in inside of the very tip of the stem The topmost 6-8 internodes are completely shortened, their leaf sheaths are strongly compacted. The solitary, yellowish white larva lies in a chamber just below the growing point; after the summer the chamber’s wall is sclerified. Monovoltine, pupation internal, after hibernation. The maximal thickness of the gall is more than twice the thickness of the stem just below.
