/ Stem mine: The mine starts in the leaf but the larva moves
to the stem (Spencer, 1976:
mine starts in a leaf, that soon wilts (to find the mine, look for
this detail). Next the larva continues as a miner of the skin of
the stem (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.
The larva is described by de Meijere (1941).
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).
Posterior spiracles each with about 20 bulbs (Spencer,
Galium mollugo is treated
as Galium album (Hedge
