Leaf-miner: Long, narrow, whitish mine. Pupation internal (Spencer,
1976: 453); anterior spiracles projecting through the epidermis.
Whitish,
upper-surface, rather narrow corridor with comparatively large frass
grains that are laying further apart than their diameter. Pupation
within the mine. The anterior spiracles of the orange-brown puparium
penetrate the epidermis (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 anterior spiracles are on relatively long stalks, each with
up to 118 bulbs; posterior spiracles on short stalks, each with
10-13 bulbs (Spencer, 1976:
453). The larva is described by Sasakawa (1961) and Dempewolf (2001:
203) and illustrated 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).
Yellowish-brown (Spencer,
1976: 453). The anterior spiracles of the orange-brown puparium
penetrate the epidermis (Bladmineerders van Europa.
Comments:
Griffiths (1980) treats
nigra as a single species with five forms. Spencer (1990)
treats nigra as a superspecies. However, he states that forms
cannot be associated with particular hosts.
