ventral view of three abdominal segments; the median white spots are rudiments of the pairwise fused prolegs.
In some full grown specimens abd 1-3 bear a weak median black spot. Contrary to what is stated by Heath & Pelham-Clinton (1976a), the row of black abdominal markings is dorsal. The larva usually lies venter-upwards in the mine.
