Silvery, upper-surface, epidermal tentiform mine, centered over the midrib or a heavy lateral vein. Contrary to Ph. leucographella, with which this species shares some hostplants, the upper epidermis looks “dirty” by the presence of numerous fine black-brown specks of frass. The epidermis remains without folds until the mine becomes strongly contracted. Young mines look like a streak of silver on top of a vein.
Rosaceae, rarely Betulaceae and Elaeagnaceae; restricted polyphagous
Amelanchier lamarckii, ovalis; Betula pendula, pubescens; Chaenomeles japonica; Cotoneaster nebrodensis; Crataegus azarolus, laevigata, monogyna; Cydonia oblonga; Hippophae rhamnoides; Malus domestica, sylvestris; Mespilus germanica; Prunus avium; Pyrus communis, spinosa; Sorbus aria, aucuparia, domestica, graeca, torminalis; Spiraea.
Betula as a hostplant mainly occurs in northern Europe (Triberti, 2007a).
Van Frankenhuyzen (1975a) reports an observation on Fagus sylvatica, details are not given (gall of Aceria nervisequa?). Reports in the literature of Corylus avellana generally are due to confusion with Phyllonorycter coryli, but that does not apply to the picture above.
Hartig (1939a) reports Alnus glutinosa; xenophagy?
Mines are found from June till October; according to Emmet, Watkinson & Wilson (1985a) the larvae live in July, and September – October.
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
LUX recorded (Fauna Europaea, 2009).

Lithocolletis corylifoliella. The from on Birch is considered by Emmet, Watkinson & Wilson (1985a) a separate form, f. betulae Zeller, 1839.
Despite its apparent simplicity this mine in reality is quite complicated (Emmet, Watkinson & Wilson, 1985a). Shortly after having started the epidermal mine, the young larva begins to make a second mine within it, in the palissade parenchyma. For a while the larve lives only, or mainly, in this inner mine. Only at a rather late stage it returns to the outer mine, and then consumes also the “roof” of the inner mine. What remains of the inner mine is a black patch in the palissade parenchyma (van Frankenhuyzen, 1975a). This patch distinguishes the mine of corylifoliella from that of Callisto denticulella (van Frankenhuyzen & Freriks, 1975b).
The mines strongly resembles those of Ph. leucographella, a species that only since 1991 belongs to the Dutch fauna (Stigter & van Frankenhuyzen, 1991a). This species basically lives on Firethorn (Pyracantha), but some authors suppose that leucographella already has made the stepover to a large number of other Rosaceae genera (Huisman & Koster, 2000a). This much is certain that leucographella forms mines on apple an hawthorn when firethorn is growing nearby. Ph. leucographella hibernates as larva (Stigter & van Frankenhuyzen, 1991a, also own observation), while corylifoliella hibernates as pupa (Emmet, Watkinson & Wilson, 1985a).
Sorbus aucuparia, Nieuwendam. The silvery epidermis, speckled with drops of frass, has largely been removed. Below it the damaged roof of the inner mine is visible (containing a very different type of frass). The larva in this mine was dead, and the roof of the inner mine was dry and brown. Otherwise the roof of the inner mine would have been green (and even more difficult to observe).
