Atherigona varia (Muscidae) ?
Greetings.

Nobody to correct me ?
So I must be right with this nice one.
#4
It certainly looks like it.
Thnks Stephane..

It is a pleasure o meet this nice fly here.
Of course, there are no doubts about genus, but species level ID isn't as easy.
I have rather large collection of Atherigona from Senegal, Egypt, Turkey and Oriental.
The only key I could found is Adrian Pont's key for Saudi Arabia. With this key I have 95-98% ID of several species: A.bredfordi, A.laevigata, A.orientalis.
A.varia absent in Saudi Arabia and absent in Pont's key. There is description of A.varia in Gregor at all key for Central Europe and key for European Russia. But in both cases descriptions have been done in knowledge that A.varia is the only Atherigona in region and are not enought to be sure in case like this (Spain) where there are several more species.
Have you Stephane (or anybody else) reliable ID specimen of A.varia? I'll be happy to see photo or ask several questions to such specimen owner

No, I never found Atherigona.
That why my answer was not sure.
I'm just beginning studying Muscidae, my collection is very very small...
#7
No, I never found Atherigona.
It is a pity - in France A.non-varia is less probable than in Spain.
I can say that in another Mediterranian country - Turkey, tiny lake Titreyen near Side I found at least 3 different species of Atherigona at once!
And I still don't know is A.varia among its or not
Someday we'll know the answer!

Rafael, I can't help but add that this is an exceptional photo, so sharp and detailed, and nice composition too!

Today at Sochi region I collected 2 Atherigona varia, now I know how it looks like!
It looks exactly as this one, so Stephane ID is correct -
A.varia
Rafael, will you please, submit in Gallery!

Again in Sochi??
you lucky man! Always travelling.
airplane?
#11
I'm happy for you Nikita, you have found it ! Not my case yet.
What was the habitat ?
#12
this one Stpehane: >> I think something like this
http://diptera.in...ad_id=6523
and next year there will be a total solar eclipse in RUSSIA! 1 August 2008.
Siberia region, Novosibirsk will testify the great event (2 minutes).

What was the habitat ?
According Gregor et al. host plant and larvae of A.varia are still unknown. I susupect I know the answer - no host plant as in case of Atherigona orientalis, but varios decaying matter. My specimens was from dead rat I was lucky to find at Imeretinsky lowland (future Olympic village of Sochi 2014
) Also some specimens from Turkey was A.varia too I guess now - and again all females and all from carrion!

Thanks for the information Nikita.
#16
It is Atherigona varia from Sochi.
2 spp with darkened t3 apical half, 1sp like on Rafael's image
#17
Opps!
It isn't intra-species variations, but two different species (also palpi and frons differs) - one A.varia, another one new for Russia another Atherigona. Which one out of 2 is A.varia I don't know again

What a geometrical fly ; all seems to be square, head, antennae. An amazing robot fly !
#19
Stephane, I had reason to be careful in species level ID of European Atherigona! I started to suspect it as soon as sent previos reply, but now I've got confirmation from Adrian Pont - my 2 species from Sochi are both new for Russia (and Central Europe) and no one out of 2 is A.varia
Nikita
P.S. Still, Rafael's image well may be A.varia (or A.pulla)

OK, I take due note of this.
What species did you find ?
