Zeugophora flavicollis (Marsham, 1802)
mine
For all the western European Zeugophora species applies: large, blackish brown, upper-surface blotch. Oviposition at the leaf underside, in a small pit, that is covered by secretion. These oviposition marks remain visible as small, transparant points. Larva yellow, flattened, with a distinct head but no feet. They live communal, and leave the mine through an upper-surface exit slit.
hostplants
Salicaceae, oligophagous
Populus balsamifera, x canadensis, x canescens, nigra, tremula; Salix alba, alba, x fragilis, caprea, myrsinifolia, pentandra, triandra.
According to Rheinheimer & Hassler (2018a) mainly on Populus tremula and only rarely on Salix.
phenology
Larvae from June to September (Hering, 1957a). One generation, hibernation as larva (Cox, 2007a; Urban, 1922a).
BENELUX
BE uncertain (see below).
NE observed (Beenen & Winkelman, 1993a).
LUX uncertain (see below).
distribution within Europe
W and C Europe, from the UK and the Pyrenees to Belarus, and from Spain to Bulgaria (Cox, 2007a; Warchalowski, 2003a). The Fauna Europaea (2007) gives rather different, certainly erroneous, information.
Urban (1922a).
