Hello,
I tend to ID this as Graphocephala fennahi. however Colour pattern is strange and does (?) not fit in anything??!
Do pattern depend on age, temperature, genus?
Size: 2-3 mm, Found: Schwetzigen, Germany, 11 oct 20
Any expert who may help?
Regards
Lothar

Hi Lothar, I agree - a strange pattern for Graphocephala fennahi but common for Zygina tiliae.

Hi Eric,

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.
