Description of adults: Examined: 1 . Forewing length: 2.6 mm; Head smoothly scaled, dark brown, bronzy golden shining; labial palpi app. 0.2 mm long, diverging downwards, grey brown, bronzy golden shining; Eyes very small, black brown; antennae about 2/5 of forewing length, dark brown, bronzy golden shining; thorax and tegulae dark brown, bronzy golden shining; forewings dark brown, bronzy golden shining, distad with purple violet shimmer; markings silvery white with golden glance: At about 1/4 a moderately broad, slightly inwardly bent fascia across the whole wing width, broadened at inner margin; at slightly more than 1/2 a narrow triangular spot at inner margin, its tip reaching across more than 1/3 of the wing width; a similar, more roundish spot at 7/10 at costa, also reaching across 1/3 of the wing width; fringe dark brown with purple violet shimmer, at apex and outer margin acute contrasting white; hindwing brown grey with violet shimmer; fringe alike, more bronzy golden shining; underside grey brown with intensive coppery glance; basis of forewing silvery, distally a light brown spot of scales; wing and fringe lightened witish-yellow in the area of the upperside spot at 1/2 at inner margin; fringe of both wing pairs grey brown, coppery shining; underside of thorax light brown grey, bronzy golden shining; segments of tibiae and tarsi at distal margins darkened brownish-violet; foretibia with epiphysis (?); midtibia with a short pair of spurs at distal end; hindtibia flattened dorso-ventrally, with long duft of hair-like scales and a pair of spurs each at about 0.45 of tibial length and at distal end; abdomen dark brown at upperside, at underside lighter grey, bronzy golden shining.

Distribution:

The species is known from Great Britain and France throughout central Europe to Ukraine, as well as from Italy, the larger part of the Balkan peninsula to Greece and also from Portugal and Sweden (Karsholt & Nieukerken 2013). As a mine on Cornus mas, it is reported here for the first time from Serbia (Kurz & Kurz 2015). Vertically, records are documented from near sea level to about 800 m a.s.l. (Kurz & Kurz 2015).

The species inhabits shrubs, hedges and wood margins with the occurence of the larval foodplant. A. treitschkiella flies in two generations per year in central Europe, with imagines in June and again in August. Larvae can be found in July and from September till November. The imagines fly in the evening, larval food uptake has been observed in the daytime (Kurz & Kurz 2015).

Larva. The larva feeds, as far as known for certainty, only in the leaves of cornel cherry (Cornus mas). The mine starts with a short galery, which soon widens to a large blotch. Fullfed, the larva cuts out an oval cocoon from upper and lower epidermis, falls to the ground and overwinters there (Kurz & Kurz 2015).

Genetics:

Following Nieukerken (in litt.), the taxon consists of two in the DNA barcode distinctly diverging clades, and therefore there may be two distinct species. Therefore, also the synonymy of A. petryi has to be cheked again. A. stachjanella, already recognized as doubtful species in Huemer and Tarmann (1993), now also falls into the synonymy of A. treitschkiella (Huemer 2013).
