Branched, sometimes stellate, brownish, very transparent, sometimes long corridor that contains almost no frass. All frass is ejected through a number of tiny openings that generally are close to a vein. Only the young larvae live as miners.
Amelanchier ovalis; Chaenomeles; Cotoneaster; Crataegus laevigata, monogyna; Cydonia oblonga; Malus domestica, ringo, sylvestris; Mespilus germanica; Prunus armeniaca, avium, cerasus, domestica & subsp. insititia, dulcis, mahaleb, persica, serrulata, spinosa; Pyrus communis; Sorbus.
Also Betula (Requena). At least in Britain Malus, Pyrus, Prunus spinosa are the main host plant (Bland ao, 2002a)
Mentioned by Elsner ao (1999a) also from “Cerasus serratula”; probably Prunus serrulata was intended.
Now and then the species is recorded from Corylus avellana, Rhamnus and Betula. A common acceptance of Birch and Rosaceae is not exceptional, but the other cases probably should be regarded as xenophagy.
Larvae mine from August to October; after hibernation they live free in the buds and among young leaves (Hering, 1957a).
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
LUX recorded (Fauna Europaea, 2009).
distribution within Europe
Almost all of Europe, but missing in Ireland and rare in the North (Fauna Europaea, 2009).
Larva reddish brown; head and prothoracic plate black (Bland ao, 2002a).
Described by Patočka & Turčáni (2005a).
Seems to be in decline (Bland ao, 2002a).
Elsner ao (1999a) list also Recurvaria leucoptera (Clerck, 1758) as a miner, living an a long series of Rosaceae, moreover, with question marks, Rhamnus and Acer. However, in the discussion of the biology of this species by Bland ao (2002a) not even a hint to a mining life style is given.
