Pegomya haemorrhoum Zetterstedt, 1838
[Diptera: Anthomyiidae]

Pegomya haemorrhoum Zetterstedt, 1838. Insecta Lapp. : 692
Aricia transversalis Zetterstedt, 1845. Dipt. Scand. 4: 1538.

Leaf-miner: Mine without spiral or tightly wound loops. Mine shallow, dorsal or ventral, greenish in transmitted light (only in small leaves sometimes full depth, but then the frass, when corridor-like, always in separate grains). One or more egg shells at the beginning of the mine on the ventral surface of the leaf.

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 are therefore included under 'Hosts in Britain' and 'Hosts elsewhere
