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

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... Greetings. Edited by Stephane Lebrun on 21-11-2007 20:00 Stephane. |

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

M. nana has got open r4+5 cell as far as I know... I have seen melanomyia in august 2006, on the bank on the other site of the lake 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 )

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 Theo |

I can't bear the thought of Theo "lost"  , 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.

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. Theo |
