Leaf-mine: Mine long and narrow, white, with frass in conspicuous, widely spaced black lumps. Pupation in the mine adjoining a vein, with anterior spiracles projecting through the epidermis (Spencer, 1976: 472). The mine is illustrated in British leafminers and Nederlandse bladmineerders. Mine of Chromatomyia primulae on Primula vulgaris. Image: Willem Ellis (Source: Nederlandse bladmineerders) Larva: The larva is described by Dempewolf (2001: 206) and Ellis (Nederlandse bladmineerders). Puparium: Varies from whitish to reddish-brown. Anterior spiracles divided into two arms; posterior spiracles each on a large, widely-separated conical protuberance, with a total of up to 30 minute bulbs (Spencer, 1976: 472). The puparium is illustrated by Ellis (Nederlandse bladmineerders).
