Plant Parasites of Europe

leafminers, galls and fungi

Phytomyza corvimontana

Phytomyza corvimontana Hering, 1930


Upper-surface corridor; the start may be lower-surface. Usually the corridor follows the midrib for some distance. Pupation outside the mine.


Asteraceae, narrowly monophagous

Achillea ptarmica.


Bivoltine: early summer & late summer (Robbins, 1991a).


Not known from the Benelux countries (Fauna Europaea, 2008).

distribution within Europe

From Sweden to the Pyrenees, and from the UK to Lithuania and Poland (Fauna Europaea, 2008).


Black (de Meijere, 1934a).


Mentioned by me in 2004 as occurring in the Netherlands, on the base of two samples of vacated mines in the province of Overijssel. However, in 2007 a sample of mines on A. ptarmica in Amstelveen, of which the mines agreed closely with corvimontana, yielded a larva thast clearly was a Liriomyza. It seems wise therefore to provisionally consider all Dutch material of “corvimontana” as L. ptarmicae.


Hering (1939b, 1955b, 1957a), Huber (1969a), Pakalniškis (1994a), Robbins (1991a), Spencer (1972a), von Tschirnhaus (1999a).
