Nemorimyza posticata:  oviposition site

detail: oviposition scar and punctures


Large, brown, upper-surface blotch with conspicuous primary and secondary feeding lines. The feeding lines are the more apparent because the semiliquid frass adheres to them. Pupation outside the mine; exit slit in the upper epidermis.

host plants

Asteraceae, oligophagous

Aster amellus; Bellidiastrum michelii; Buphthalmum salicifolium; Solidago canadensis, gigantea, virgaurea.


Larvae in Jun-August and September-October (Hering, 1957a).


BE recorded (Ellis: Torgny, Montauban).

NE recorded (de Meijere, 1934a).

LUX recorded (Ellis: Kautenbach, Dudelange).

distribution within Europe

From Scandinavia to the Iberian Peninsula and Italy, and from Ireland to Belarus and Hungary (Fauna Europaea, 2008).



Dizygomyza posticata; Agromyza terminalis Coquillett, 1985; A. taeniola Coquillett, 1904; A. argenteolunulata Strobl, 1909.


The beginning of the mine follows a very constant, and seemingly unique pattern. Oviposition is close to the leaf margin (there is well-visible oviposition scar). A little distance more towards the interior of the blade there are one or two small perforations. They remind of the “test punctures” of Antispila metallella.
