Antispila treitschkiella (Fischer von Röslerstamm, 1843)
Cornus mas, Nieuwendam; early October 2009 the species again reached pest densities; almost no leaf was less heavily infested (this leaf moreover had been visited by a leafcutter bee [Megachile]).

Oviposition usually close to the leaf margin. From there starts a corridor of about 1 cm; it contains much frass, is often somehat tortuous in its beginning and as a role closely follows the leaf margin. After a moult the direction reverses (picture) and the larva starts making a full depth blotch that can become several cm long and wide. Here the frass is lying in scattered grains. The full grown larva covers an oval section at the margin of the blotch with a light brown pergamon-like layer of silk, cuts this loose and drops within it to the ground. The excision that is made is about 4-4.5 mm long.
Contrary to A. metallella the female does not makes “test punctures” before ovipsition (Dziursynski, 1958a; Heath & Pelham-Clinton, 1976a). Also contrary to metallella the larva has a row of black spots on all abdominal segments, easily visible without opening the mine. (The larva usually lies belly-up in the mine.)
Cornaceae, narrowly monophagous
Cornus mas, sanguinea.
In the Netherlands, and also in other parts of Europe the species almost exclusively occurs on the ornamental shrub C. mas, but in southern Belgium it also is seen often on C. sanguinea (Chris Snyers in litt.)
According to the British literature occupied mines are found from end-August to early October (Heath & Pelham-Clinton, 1976a), but in the latest years another, early larval generation occurs in July, that produces adults in August (Huisman ao, 2005a).
Until recently a rare species in the Netherlands, but strongly expanding (Kuchlein & van Frankenhuyzen, 1999a). From 2003 here and there mass occurences are seen (van As & Ellis, 2004a).
Hibernation as larva, in the case ( Kuchlein & van Frankenhuyzen, 1999a).
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
LUX not recorded (Fauna Europaea, 2009).
distribution within Europe
South of the line Britain – Ukraine, but missing in the Iberian Peninsula and the Mediterranean Islands.
Described by Patočka & Turčáni (2005a).
Antispila petryi Martini, 1898; A. stachjanella Dziurzynski, 1948.
An almost forgotten publication by Dziurzyński (1952a) has created doubt about the long-accepted synonymy of petryi and treitschiella. According to Dziurzyński petryi mines exclusively on Cornus sanguinea, while treitschkiella feeds only on C. mas; also the larva of petryi haas a black spot n the mesonotum that is missing in treitschkiella. A paper dealing with this confusion is in preparation (van Nieukerken et al.).
Usually the oviposition is close to the leaf margin; but in some Dutch populations about 50% of the mines is free from the leaf margin.
