Phytomyza stolonigena Hering, 1949
Ranunculus repens, Oldenzaalsche Veen
same mine, enlarged
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.
Ranunculus acris, bulbosus lanuginosus, lingua, repens.
Larven in August-October (Hering, 1957a).
BE recorded (Mortelmans ao, 2013a).
NE recorded (Ellis; one single locality).
LUX Some empty mines were found in Kautenbach in early May, 2003 on Ranunculus ficaria that possibly belonged to Ph. stolonigena.
distribution within Europe
From Britain to Poland and Lithuania (Fauna Europaea, 2008).
The mine rather resembles to one of Orthochaetes insignis. That mine is really full-depth, more branched, and has sides that are irregularly eaten out (Hering, 1949a). Of course also the presence of feeding punctures indicated an agromyzid.
