arbustorum... (and by the way, it's nemorum, not nemoralis) Wink

Thank you Andre, the spelling is noted also, but how do you separate them?? Frown

From this point of view, for instance, the shape of the stigma, which is long (and has two colours: dark/brownish).

Andre, I have just noticed that despite Guido Van de Weyer's efforts at determining all the 4,000 plus syrphid specimens I have sent him, E. nemorum is not on the list of Syrphidae for the National Park (155 species so far recorded). So does it have a visa problem Grin, or does it just not like Greece?Sad
