Leaf-mine: Details unknown.

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.

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).

Hosts in Great Britain and Ireland: Currently unknown.

Hosts elsewhere:

Woodsiaceae        
Cystopteris fragilis Brittle Bladder-fern British Wild Flowers by John Somerville et al. Michelsen in litt. to Mike Ackland
