Zeugophora subspinosa (Fabricius, 1781)
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, transparent points. Larva yellow, flattened, with a distinct head but no feet. They live communal, and leave the mine through an upper-surface exit slit.
According to Augustin (1998a) the commonest Zeugophora.
Salicaceae, monophagous (?)
Populus alba, carolinesis, nigra, tremula.
P. tremula is the main host plant; Augustin also mentions Salix, but according to Rheinheimer & Hassler (2018a) only records from Populus tremula are trustworthy.
Larvae from June – September (Hering, 1957a).
BE uncertain (see below).
NE observed (Beenen & Winkelman, 1993a).
LUX uncertain (see below).
distribution within Europe
From Norway and Siberia to Spain and (Cox, 2007a; Warchalowski, 2003a). The Fauna Europaea (2007) gives quite different information.
Grandi (1938b) gives an extensive description; mandible with 2 teeth.
See Warchalowski (2003a) for a key to the beetles.
