Leaf-miner: Large full depth blotch, covering the entire distal part of a pinnula. The mine begins near the top, where an elliptic egg shell is attached to the underside of the rachis. Larva solitary. The mine contains much frass (Bladmineerders van Europa). An upperside blotch at the tip of a pinna lobe (British leafminers). 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 larva is described by de Meijere (1911, as Hylemyia cinerosa) and illustrated in (Bladmineerders van Europa). The cephalopharyngeal skeleton with the upper process shorter than the lower. Mouth hook with only one tooth. 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). Described by Stork (1936a), as Pycnoglossa cinerosa) (Bladmineerders van Europa). Comments: Ackland in Chandler(1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.
