I think this is a Leopoldius species but not sure which species exactly. I have browsed through the net and I cannot find anything similar. All photos below are from the same specimen taken about a week ago in the Rhone Valley in France - calcareous grassland. Can anyone recognise which species it is ? Thank you.

I am unable to attach a photo, I have reduced the size to 72dpi and 600 pixels, have followed all the instructions... I am not sure what I am doing wrong.

Maybe there are spaces in your filenames?

"Attaching files to forum posts is restricted to the following types: gif - jpg - png - zip - rar - tar.
Please make sure that you use lower case, because attachments with extensions in upper case (capitals) are rejected. The maximum size is 200000 bytes. Other requirements are: no spaces in the file name, not dots in the file name other than the one in front of the file extension and only alphanumerical characters and '-' and '_' are allowed."

I am trying again, I have reduced the quality of the image and have cropped it more. In case it fails again , the image size is 535x526 and 20.7Ko - I am not very good with photo resizing and computers in general so any comments are welcome

Hello Sylvie, the good news: your image is successfully transfered!
The bad news: only female Leopoldius can be clearly identified. Do you have a lateral view of this fly?

If you have another photo simply use the button "NEW REPLY" in this thread.

Hello Erik,

Thank you for your reply. I have attached another photo. I think it is a male unfortunately. If you need more photos, please let me know. I tend to photograph insects from all positions for identification.

Thanks for the photo, Sylvie. I'm still not sure if it is a Leopoldius sp., which should have a very short tongue. A striktly lateral image could help (the beak must be visible). A view of the face would help, too.

Hello Eric,
Thank you again for your reply. Please see attached a photo of the face with the tongue which seems long to me.

Hello Sylvie, I think we are very close now and I suspect it's a male Abrachyglossum capitatum.
See De Bree (2012): The conopid fly Abrachyglossum capitatum.
We could be sure if you have a detailled photo of the 3rd antennal segment showing the spikes on the tip.

And I think you are right - a repetitive error on my part! Thanks Henrik!
