Aulagromyza lucens (de Meijere, 1924)

Leaf / Stem mine: The mine starts in the leaf but the larva moves to the stem (Spencer, 1976: 316).

The 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, 1976: 316).

Comments: Galium mollugo is treated as Galium album (Hedge Bedstraw) by Stace (2010).

Hosts in Great Britain & Ireland: Currently unknown.
