Salix alba, Mddelburg: a large part of the larval life is passed as a bark miner on young shoots; © Camiel Doorenweerd
Very long, purely epidermal, corridor, either upper- or lower-surface. The mines are restricted to the terminal leaves of young shoots. The mine passes from one leaf to the other by way of the shoot epidermis. Frass in a broad fuzzy central line. The corridor ends upon a leaf margin, where pupation takes place under a folded part of the margin, not in an evident cocoon.
Salix alba, babylonica, daphnoides, euxinia, lanata, matsudana, purpurea, x salamonii, triandra, viminalis.
In the Netherlands S. alba is the main hostplant by far. This evidently is no general rule. Emmet ao (1985a) describe purpurea as th main host, without even mentioning alba. And for Hering (1957a) purpurea is the hostplant par excellence.
Found by Ben van As also on Salix pentandra.
Found once by Kasy (1965a) on S. caprea (pupation at the base of the leaf); considered xenophagy.
According to Delplanque (1998a) also regularly on Populus alba: confusion with Phyllocnistis xenia
Larvae in June – July and August – September (Emmet ao, 1985a).
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
LUX not recorded (Fauna Europaea, 2009).
distribution within Europe
Probably almost all Europe, but missing in Ireland, perhaps also in parts of the Balkan Peninsula (Fauna Europaea, 2009).
Described by Lüders (1900) and Grandi (1931a, 1933a).
The species is expanding. Huisman & Koster (1999a) still considered the species rather scarce, but already Huisman, Koster, van Nieukerken & Ulenberg (2001a) reported findings in urban situations. Now it is one of the commonest miners in the Netherlands. Similar signs come from Belgium (Phegea, 2009) and Britain (Langmaid & Young, 2009a).
Where willows are grown commercially, in monoculture, Ph. saligna may become a serious pest (e.g., Noreika & Smaliukas, 2005a).
