The leaf and stem mines of British flies and other insects

(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

by Brian Pitkin, Willem Ellis, Colin Plant and Rob Edmunds


Hydrellia flavicornis (Fallén, 1823)
[Diptera: Ephydridae]

Notiphila flavicornis Fallén, 1823d. Hydromyzides Sveciae : 10
Notiphila erythrostoma Meigen, 1830
Hydrellia erythrostoma (Meigen, 1830).
Hydrellia flavicornis (Fallén, 1823d).

Leaf-miner: Shallow upper-surface mine that enters the blade from the petiole. Pupation internal, often in midrib or petiole (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).

Comments: Irwin and Chandler in Chandler (1978) did not indicate whether their host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.

Hosts in Great Britain and Ireland:
