324 Phyllonorycter sorbi
(Frey, 1855)Wingspan 7-9 mm.
Distributed throughout the British Isles, this species is generally commoner in the northern half. It flies in April and May and again in August.
The forewing colour is golden brown but is often suffused with blackish on the outer half. The white markings are well defined and partially bordered blackish.
The larva feeds in a leaf-mine, which is wrinkled on the underside and curved into a tube on the upper surface. The whole leaflet is often strongly contorted. The most usual foodplant is rowan (Sorbus aucuparia), but it is sometimes found on bird-cherry (Prunus padus) and other species of Sorbus including Swedish whitebeam (Sorbus intermedia).
