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).

notes

See Warchalowski (2003a) for a key to the beetles.
