can anybody solve this mystery conclusively? to me it looks good for baltic structurally but it has the tail of a GBBG. such double subterminal bars occure in argentatus, marinus, michahellis...why not in fuscus?

Hi

Why not a marinus? It looks like the size is similar to the adult one in the first pic, the young one is a few meters behind in the air, thats all
