[Diptera: Anthomyiidae]

Botanophila fugax (Meigen, 1826).


Stem-borer: Larva feeding in stems and buds (Ackland in Chandler, 1978: 227).

Elongated-oval eggs are deposited at either side of the leaf. They have irregularly keeled ribs running from one pole to the other (Miles, 1952, 1953).

The larva primarily lives as a borer in stem and petioles, but is capable of making corridor-like excursions in the lamina (Bladmineerders van Europa).

Although 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).

Comments: 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'.
