Leaf-mine: Larvae feeding singly, forming a long, widening mine on the upper surface of the leaf, which is generally limited to one side of the leaf. Pupation external, puparium glued to the leaf near the end of the mine (Spencer, 1976: 128). Larva: The larva was decribed by Griffiths (1963) and in Nederlandse bladmineerders. Puparium: Varying from black to reddish; posterior spiracular processes distinctly separated, each with 3 bulbs (Spencer, 1972b: 34 (fig. 97); Spencer, 1976: 128).
