Leaf-miner: A whitish-greenish blotch. Pupation external, on the ground (Spencer, 1972b: 43, fig. 140; Spencer, 1976: 306-7, fig. 552). A chacteristically pale whitish, usually upper-surface, primary blotch. There is an initial corridor, but traces of it are almost always overrun by the later blotch. The mine is quite opaque; only by opening it can it be ascertained if the mine is still occupied. No feeding lines are apparent. Unlike other blotch mines thay may occur here, Calycomyza mines are totally flat. Pupation outside the mine (Bladmineerders van Europa). A whitish blotch mine occuring on the upper leaf surface. Starts with a short corridor and does not show feeding lines. Superficially similar to the lepidopterous mine made by Leucospilapteryx omissella, but the latter mine turns purple as it ages (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 yellowish larva is described by de Meijere (1925). Sasakawa (1961) and in (Bladmineerders van Europa). 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). Reddish-brown, deeply segmented; posterior spiracles each with 3 bulbs (Spencer, 1976: 306). Hosts in Great Britain and Ireland:
