Aulagromyza orphana (Hendel, 1920)


Leaf / Stem-mine: The mine begins in a leaf, that soon withers (sign to look for, when trying to find this miner). The larva continues living as a miner in the skin of the stem (Bladmineerders van Europa). Pupation external (Spencer, 1976: 320).

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) and Dempewolf (2001: 167, as ? Aulagromyza orphana). Posterior spiracles widely-separated, each with an ellipse of numerous small bulbs (Spencer, 1976: 320).

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).
