initially linear mine, which at second instar develops into a large
whitish blotch with conspicuous black frass. The early linear mine
is frequently entirely enveloped by the blotch but is detectable
by the alternate irregular strips of frass. Pupation external (Spencer,
first part of the mine consists of a long, slender upper-surface
corridor. After the first moult this changes into a large primary
blotch without feeding lines. Frass in the corridor in short, somewhat
angular thread fragments, towards the end even in grains. Frass
arranged less closely along the sides than in A.

The frass is conspicuous in the mine and the mine is initially linear, then develops into a white blotch, often enveloping this early mine (British
Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.
The larva is described by de Meijere (1934) and illustrated in Bladmineerders van Europa.
Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).
Reddish-brown, deeply segmented; posterior spiracles on short conical
projections, each with 3 bulbs (Spencer,
