Larva feeding in stems and buds (Ackland in Chandler,
eggs are deposited at either side of the leaf. They have irregularly
keeled ribs running from one pole to the other (Miles, 1952, 1953).
larva primarily lives as a borer in stem and petioles, but is capable
of making corridor-like excursions in the lamina (Bladmineerders van Europa).
previously recorded as a miner in stems of Sambucus, Botanophila
fugax is a common saprophagous species, the larvae normally
feeding in the soil (Griffiths, pers. comm.).
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 Miles (1952).
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).
Ackland in Chandler (1978)
did not indicate whether his host records were British or Foreign
and are therefore tentatively included under 'Hosts in Britain'
and 'Hosts elsewhere'.
