Phytomyza stolonigena Hering, 1949
[Diptera: Agromyzidae]


Phytomyza stolonigena Hering, 1949c. Entomon. 1: 208
Phytomyza stolonigena Hering, 1949c; Spencer, 1990. Host specialization in the World Agromyzidae (Diptera) : 22, 43, 45 (fig. 165), 50.


Leaf-mine: The larva mines in the petiole, from where it makes corridors fanning out in the blade. The corridors are parallel-sided, little branched and almost full-depth. In fresh mine primary feeding lines are visible. Pupation outside the mine (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.

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).

Hosts in Great Britain & Ireland:

Ranunculaceae        
Ranunculus repens Creeping Buttercup British Wild Flowers by John Somerville et al. Spencer, 1990: 43

Hosts elsewhere:

Time of year - mines: August-October (Hering, 1957).

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: London (Hampstead) (Spencer, 1990: 43). Main Argyll (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Germany (Mecklenberg) (Spencer, 1990), The Netherlands, Luxembourg (Bladmineerders van Europa), Lithuania and Poland (Martinez in Fauna Europaea).
