Cornutrypeta spinifrons (Schroeder, 1913)
Leaf-mine: Broad corridor overlying the midrib. The mine has a number of side
branches that distally widen strongly, and may coalesce. Primary
and secondary feeding lines very conspicuous (Bladmineerders van Europa). Pupation external, in soil.
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 larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue.
Posterior spiracles with three elongated Bulbs (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).
Yellow; anterior spiracle openings arranged in large arcs, not elevated
on a fan-like structure; posterior spiracles each with a central
opening larger and more raised than the lateral openings (White,
Uffen in Chandler
(1978)did not indicate whether his host records are British or Foreign
and are therefore tentatively included under 'Hosts in Britain'
and 'Hosts elsewhere'.
Hosts in Great Britain & Ireland:
of year - mines: Currently unknown.

in Great Britain & Ireland: Recently recorded only from
Kent (White, 1988) and Perth
(Alva Glen) (Bland, 2005: 170).
There are old records (pre-1960) for Hereford and Lancaster (White,
