Mine of Cornutrypeta spinifrons on Senecio ovalis Image: Willem Ellis (Bladmineerders van Europa)

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: Posterior spiracles with three elongated Bulbs (Bladmineerders van Europa).

Puparium: 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, 1988).

Comments: 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'.
