Hi
* locality - Silgueiros - Viseu - PORTUGAL
* date - 2007.08.24
* size - 6 mm (medium fly)
* habitat - open land
* substrate - on Mentha sp. flower
Is this fly a male?
This Conops seems to have much fewer yellow comparing with the Conops flavipes. And it has wings with spots..
The transition between the head and thorax is unusual. :s
EDIT----> Title changed from "Another (strange) Conopidae - Conops ??" to "Syrphidae - Ceriana conopsoides" and then to "Syrphidae - Ceriana vespiformis"

not good.. (blurry)
but the head is very similar to Chrysotoxum intermedium (Syrphidae)! :|
See a photo taken by myself here for compare the two :

Congratulations, Jorge, you fell into a familiar pitfall
It's Ceriana conopsoides (or another Ceriana) in the family Syrphidae.
There is a reason why it's called conopsoides !!
Look at the antennae, they are implanted on a bizarre conical projection of the forehead. Unique.

oh... no. great mimics with Conopidae! Really I thought this was strange for conopid... :S
It seems that this is rare.. :)

I was blind because I didn't take a look to wing venation!!! :| Typical wing venation for Syrphidae!! This is the best mimics between 2 families (Syrphidae <> Conopidae) I've seen so far.
Really the names fits very well: conopsoides -- similiar to Conops. :S
Thanks, Theo! More one for the gallery. :)

I agree it is Ceriana conopsoides. I took some photos of another one in Lisbon, Portugal.

Hello,
I agree with
Ceriana, but no with
conopsoides. Entirely yellow scutellum and mostly yellow femora indicate
Ceriana vespiformis.
Greetings.

HI Stephane,
You are most probably right. I had a disclaimer formulated on the species level, to lazy to get to my books.
The colouration on the scutellum is crucial, yellow either bicolor, but I can't remember it by heart.

I just checked the gallery, Stephane is completely right:
This is a male C. vespiformis.
Most common species on the Iberian peninsula.
