Phytomyza corvimontana Hering, 1930

Diptera, Agromyzidae

mine

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

hostplants

Asteraceae, narrowly monophagous

Achillea ptarmica.

phenology

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

BENELUX

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).

puparium

Black (de Meijere, 1934a).

notes

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.
