First posting, problem with pic!

The picture has to be about 650 pixels and the file's name whitout a enter between the names.
At best you give a number...1 or 3 or 45 ...and save than.

Succes !!

It is not a Diptera, but a Hymenopera (so this posting is in the wrong forum; even though it's a Diptera-site, Paul has been so good to create another forum here: http://www.dipter...forum_id=6 ).

Your pic shows a bee, probably: Andrena cineraria (Apidae).

Compare with: http://www.nederl...HCYFAYNPKA
(I think biopix shows vaga or another species)

t seems to to me that the cubital cell number one is subdivided... Bombus sp. ?
Brush on the tarse! ?

Never a Bombus. Andre was right with Andrena cineraria, a female. The only species, what can be confused with cineraria, is its sister species, Andrena barbaraea, what occurs in the Alps (and probably also out of it, but the species is badly known).

Why cubital I is subdivided by a fine vein (Zoom), not a character of Andrena! Proportions of the very broad abdomen at the beginning!
Why a russet-red brush (Zoom) on the tarse I internal, at Andrena brushes long on the beginning of the f?mur!

For once, I do not understand! ;)

Ok, I agree (I overlooked the detailed version of the photo). It seems to be a Bombus, which is completely worn down, and lost all hairs of gaster.

Thank you Christ ian, you are stronger than me and usually I recognize the exactitude of your determinations but there really I hesitated! ;)

And so I learn as well... not a hymenopteran specialist at all! :o Maybe if The_Finn had mentioned date of the picture, he wouldn't have confused me. Very good and open-minded thinking cthirion :)
Could be a very old queen then, weakened and about to die very lonely; she's done her work :(

The picture date was 19 august 2006. The fact is that the insect was dying, died about an hour after the pic!

From Pierre Rasmont: In finland, possible Bombus veteranus, form m?lanique in S.

or sylvanus ?
