parasite

The adult beetles create ± 6 mm large windows in the upper side of the leaves, mainly along the margin (Gallardo & Cárdenas). The females make during their lifetime about 30 leaf rolls, each one containing one egg. To this end she first gnaws a deep wound in the upper side of the midrib, also in thicker side veins. At either side the lamina is cut from the margin down to the midrib. Working from the leaf tip the withering apical section of the leaf is then folded into a compact wad that serves as food for the larva. Sooner or later the leaf rolls fall to the ground.
