Phytomyza kaltenbachi Hendel, 1922
The first part of the mine is a lower-surface, thread thin and very long, shallow, initially whitish, later brown corridor that winds through the leaf several times and crosses itself repeatedly. Frass here in a narrow central line. After a moult starts the second part of the mine: also a corridor, with irregular sides and clear primary feeding lines. Frass in this second part in black strings. Puparium within the mine, in a lower-surface pupal chamber (Hering, 1957a; Spencer, 1976a).
Maček (1999a) also mentions Caltha palustris; this requires confirmation.
Mines in June-August.
Not known from the Benelux countries (Fauna Europaea, 2008).
