Populus cf viminalis, Belgium, prov. Namur, Furfooz, Parc National de Furfooz © Stéphane Claerebout
Populus canescens, Amsterdam: feeding punctures

Populus tremula, België, prov. Luik, Heid des Gattes-Aywaille © Carina Van Steenwinkel: the mine to the left is of A. albitarsis; more to the right, much darker, a mine of Zeugophora spec.

the two mines lighted from behind; the orange spot is the characteristic oviposition scar of Zeugophora; the arrow points to the young Zeugophora larva, that has strayed into a foreign mine. The albitarsis-larve is fully grown and already has made its exit slit.
mine
Elongated, upper-surface blotch, on Poplars much larger than on Willows. At first the colour is green, but this quickly turns into an opaque brown. The larvae (maggots) distinguish these mines from those of Leucoptera sinuella and species. They are yellow, and often live communal. They leave the mine before pupation; the exit slit is in the upper epidermis.

Agromyza populi Hendel, 1920 nec (Kaltenbach, 1864); Agromyza lygophaga Hering, 1937. The homonymous name Agromyza albitarsis Zetterstedt, 1848 has caused a lot of confusion; it is a synonym of A. alnivora Spencer, 1969.
