Hi Goosey,
Well, I'm afraid I'm pretty much with Paul all the way on these - that is
including the scorching sensation as soon as I start to talk about Diptera
However, a good dutch ref for syrphids is the
site by Han Endt (
Eristalis,
Dasysyrphus).
Also, maybe try having a look at Wolfgang Rutkies'
syrphidae.de (or directly to the
Eristalis or
Dasysyrphus pages) - has a good
intro too.
Both sites are quite reliable to render correct ID's (where many other internet sources are a tad "iffy"), but also both sites do
not have images of
all species listed for NL. For a list of dutch syrphids maybe check nederlandsesoorten.nl:
Syrphidae /
Eristalis /
Dasysyrphus or faunaeur.org:
Syrphidae /
Eristalis /
Dasysyrphus
Just to participate in a wild guessing frenzy: My 2ct would be on a female
Dasysyrphus venustus and an
Eristalis tenax (female too???) - but please note that I own a grand total well over 10 Euros (maybe even 11), so the 2ct don't amount to much
Hope it helps you in your own searching efforts though.
Cheers! Arp
