large, irregular blotch mine with a short linear section in the
first instar which is frequently entirely enveloped in the fully
developed mine and may then be no longer visible (Spencer,
the only character differentiating it from abiens is the presence of several larvae in a fully developed mine of abiens and just one in myosotidis (Bladmineerders van Europa).
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.
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).
