Hi, I have a problem again with these. This time there are long setae on meron, so it should be Calliphoridae. As far as I can see, the coxopleural streak exists like with Lucilia. The colour is strange with yellow legs, brown-yellow meron and anepimeron. Am I totally wrong again ?? June 5. 2007 Helsinki, Finland.

My first impression is that it is one of those white-calyptrated boreo-alpine members of the genus Calliphora (yes, you didn't think of that !), the genarum-subgroup.

Try Rognes.

Interesting point. I do use Rognes book but ..... If we are looking for Calliphora species: both calypters are white; that leaves three possibilities; it has two inner and one outer ph setae and then the only possibility should be subalpina. But... it should have 4 pairs of marginal scutellar setea and this one has three; face and parafascial should have yellow ground colour with yellow dusting but this one has white :o Arista has very long hairs, so that will skip genarum out and stelviana has too many things that will not match so I'm in trouble :@

OK, let's go about this more methodologically:

* are the calyptrae hairy, at least ?
* what about the stem vein in the wing (have a very close look)

And the answers are no and no. That's why I at first ended to Malanomyinae but as far as I understand there is a coxopleural streak and that is confusing me. Thank You so far Theo :)

I see the problem more clearly now.
It runs indeed to Lucilia, given all information.
I'm not an expert on aberrant species in this genus, some Lucilia can be very bluish. But it really doesn't look like a Lucilia (non-scientific argument that works often quite well).
Thanks for getting me frustated as well

Yes, I think I will put it aside and wait. I just hope, that it's not a strange coloured very common Melinda ;)

Hi Jari & the diptera.info guys and gals. I've been busy with many things so I've spent less time on this site than I used to. Hopefully things will get better soon. It's still one of my favourite sites and I love you all :)

Melinda was my first impression.

Maybe it is that simple, Melinda.
There seems to be no alternative.

Somehow, it didn't strike me as Melinda.

Oh, I forgot, it can't be Melinda, because it was a coxopleural streak , now can it ?

Here You have a very bad picture of posterior spiracle and with the streak. The camera adapter for my new microscope has not arrived yet, so picture is bad. The strange meron colour is visible too. In fact this was with my Melinda specimens, but the yellow legs was the first thing that made me wonder. Maybe it's just a mutant specimen of very common gentilis.

Thank's for Your attention.
