Pegomya conformis (Fallén, 1825).

Leaf-mine: Mine indistinguishable from that of P. hyoscyami (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: Ackland in Chandler (1978) did not indicate whether his host records were British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere

Hosts in Great Britain and Ireland:

Time of year - mines: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Widespread in Britain including Easterness, North Devon, South Lancashire and West Suffolk (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including The Netherlands (de Meijere, 1939), Belgium (Gosseries and Ackland, 1991), Denmark, Germany and Sweden (Michelsen in Fauna Europaea).

Also recorded in China, Japan and Egypt.
