Hi Eric,

a strange pattern for Graphocephala fennahi but common for Zygina tiliae.
as there are at least 16 species of
Zygina in Germany, several of them with a similar pattern, how do you arrive at
Z. tiliae without knowledge of the host plant? At the moment
Z. flammigera is very common here (on
Carpinus etc.).
@Lothar:
Graphocephala fennahi measures 7-9 mm. The one below I did not find on
Rhododendron in our garden (as usual), but on
Rubus fruticosus agg next to a forest path three days ago.
