Is it possible to identify this primary nest from the shape / size or do I need an actual sighting for identification as AH? I understand that primary nests of wasps and hornets are pretty similar.
Context: border italy-france (AH is well established there), 8cm diameter
EDITED: I see yellow legs here?
Thanks
