Achillea ptarmica, Amstelveen, Schinkelbos

mine

Narrow brownish corridor, either upper- or lower-surface. Frass in strings or pearl chains. Pupation outside the mine. In small leaves the mine can be full-depth and occupy the entire leaf (Buhr, 1932a). At least in Achillea millefolium mines are generally found in the top half of the leaf.

host plants

Asteraceae, oligophagous

Achillea distans, millefolium, ptarmica, seidlii; Anthemis arvensis; Glebionis coronaria.

synonyms

Liriomyza aesalon Hering, 1936; Liriomyza chrysanthemi Hering, 1956; Liriomyza millefolii Hering, 1927 [Spencer, 1971a, 1976a], L. pilosa Spencer, 1969. L. ptarmicae has long been confused with L. pumila, that in his turn is considered now a synonym of L. strigata.

notes

In 2004 I reported in this site Phytomyza corvimontana as a new spcies for the Dutch fauna, on the basis of two samples of vacated mines from the province of Overijssel. However, in 2007 I collected mine material on A. ptarmica in Amstelveen that by its mine agreed closely with corvimontana (in particular in the fine-grained texture of the frass, see the ©), but which was inhabited by an obvious Liriomyza larva. For the moment I assume therefore that the Dutch “corvimontana” provisionally can best be placed along with L. ptarmicae.
