hi flyforum,

I think this is a Calliphoridae sp.

Do you have any idea about species?

size > 10mm

p.s. on the wingedge I see a couple of some little bristle's?

Hello Robert, I see very few bristles on thorax and abdomen, what makes me think about Phormia regina. Although many important characters are not visible: row of hairs on radius-stem, white hairs on upper calypter, other characters like yellow colour of basicosta, anterior spiracle and palpi are discernible.
Where did you see this rare species, that I met only 2x in 40 years? Jan H.C.Velterop

Just checked Rognes and everything seems to fit for Phormia regina (which I have never seen). I think the bristles that look like they are on the costa are actually on the hind tibia.

Submit for gallery please.:D

Thank you Jan, Susan and Joke for your reaction,

I found this fly yesterday in the afternoon in the southpart of the Amsterdam forest.
There is a path with young growing Fraxinus excelsiors, from the ground up to the sky.
There you can see many kind of flies, sunning, flying and doing much more..

I took several pictures, also more from the side.
You can see the yellow coloured basicosta and white hairs on the upper calypter.
Some other characteristics you called, I cannot find yet. (I am struggling with all these terms and things..)
But it was a wonderfull nice green fly, obvious.. and I was happy I saw something new next to the Calliphora vicina's I saw the last time.
But I didn't realise that this fly was so rare?

Looked it up in the Checklist of Diptera (Paul Beuk) and the last one seen was in 1905 in Hilversum (Netherlands)
So you are the second one, seen this species in the Netherlands...
(As far as I know);)

Just picked up this thread http://www.dipter...d_id=11457

Yellow palps, very dark shining frontal vitta, very short looking pre-sutural acr - Theo could very well be right.

Thanks Susan,

I am trying to find the following terms:

- row of hairs on radius-stem
- very dark shining frontal vitta

Can you give me a hint?
I like to know them ;)

Robert - the frontal vitta is the stripe running down from the top of the head to the base of the antennae. Vitta = stripe, plural vittae. The frontal vitta is on the frons, and the term is often used interchangeably.

hi Tony and Susan,

Thank you for your tips.

I see the frontal vitta, and this one is dark (black)
I have found the row of hairs, on the radius-stem - not from an favorite view, but ther is obviously a row of hairs -

Following the discussed item's, this must be Phormia regina?!
Is it the female of this species?

I sent some pictures to the Diptera Gallery B)

Phormia regina
