From midwest Sweden 2001-JUL-19. At first glimpse I thought these were the same fly, but it wasn't. Perhaps it is female and male of the same species ... like Eristalis intricaria?

It is Eristalis intricaria. Similar species is the Eristalis oestracea but he have white scutelum and diferent tars 3 (are red) .

Correct. Female above male below. Eristalis intricarius (note genus name is male gender)

Thank you Tony and Mielczarek. The choice of names seems to be very personal. I wish there where a standard all could agree on. In Fauna Europaea it says Eristalis intricaria. Until the diptera is added to the Swedish Report System for Invertebrates I can't say what it will be named here in the cold dark north ...

Mmmm... I have to say that I tend to follow the British Check List as on the Diptera Forum website. http://www.dipter..._intro.php
As a rule, Peter Chandler is very fussy about getting things right. It isn't a matter of personal taste. There are rules which should be followed so that we can all use the same names, and end up with a stable, agreed list.

I didn't mean that everyone could make their own names up, and certainly not that you made a mistake, but it's a fact that not all follow the same standard. I'm not getting into a debate about this. I think often there are a choice of preserving an old faulty name or choosing a new proper one that might add to the confusion, because when you change a name there are going to be two names for the same species in literature etc ... When I report my findings I have to use the name that is used in Sweden to be able to report it at all.
