Silly me, the filesize was too big. The picture should attach this time.
This looks like Eristalinus sp., however unlike the other one I have collected this one does not have the eyes touching. Sexual dimorphism?

This is the one collected earlier, Eristalinus sp., male.

This is the difference between sexes - eyes touching - male, and separated - female. It doesn't always work with syrphids though.

Glad to see you're now collecting.

Thanks Jason.
I've been collecting since 1989.
Cheers, Graeme
