Top is Scaptomyza pallida of the Drosophilidae.
Bottom maybe Rhinophoridae?
Please, keep unrelated queries in separate threads. Wink

The 2nd one is close to Melanomya nana (Calliphoridae).

I think that used to be Rhinophoridae, right?

Thank you very much Kahis and Paul,

I didn't count on ID on specieslevel!
And what a small kind of Calliphoridae (Melanomya nana).

In:
http://www.nederlandsesoorten.nl/get?site=nlsr&view=nlsr&page_alias=conceptcard&cid=0AHCYFBCXNXA&q=nana
this fly is now under Calliphoridae

It was Rhinophoridae?

Hello,
I had asked the question and Theo had answered here.
Kahis didn't say it was Melanomyia nana, but close to.
M. nana has got open r4+5 cell as far as I know... Wink

Greetings.

Yes, it was in Rhinophoridae to (IIRC) the mid-80's.

I have seen melanomyia in august 2006, on the bank on the other site of the lake Wink
What I remember was that this fly got much darkener wings and indeed open R4 +R5 cell
(see photo)

I don't think it is melanomyia, but what else?
It's a pitty I don't have more pictures..

The picture underneath, I took last year (yes I made progress in my pictures Wink)

Number 2 is a surprising creature, I though Kahis was right, but the topcel is stalked. There is no Rhinophoridae matching this description. We can't see the abdomen, but it has to me a very Anthomyiidae - impression and I have difficulty to believe it's either Tachinidae or Rhinophoridae, I know, despite the fact that the M-vein is curved.
I'm lost

I can't bear the thought of Theo "lost" Sad, so offer a suggestion that the second fly might be something like Angioneura acerba (now Calliphoridae, formerly Rhinophoridae)? I know this species normally doesn't have a petiole. Unfortunately I don't have a specimen to hand to check the other features.

(I will have a look tomorrow, and I'll try to find this little creep Wink )

Tony, good suggestion. I had considered it, and rejected for the reason you mention. However, Angioneura is rather rare, so maybe it's more variable than we imagine.
