large blotch mine, several larvae feeding together (Spencer, 1972b: 31).
dozen eggs are deposited in a semicircle at the leaf underside.
After hatching the larvae eat themselves a communual corridor. After
the first moult they begin the making of a very large, dark brown
communal blotch, with conspicuous secondary feeding lines (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.
The larva is 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).
