Dear All,

www.naturedugard.org/images/4/3333.jpg

I took this photo in South of France, Gard, Fournès, the 21/06/2011.

On insecte.org forum we think to a Bombylisoma because of the nervation. But I can't find something similar in some pictures seen on the Web.

Which will be your diagnostic ?

Thank you,


Jean-Laurent Hentz
Beaucaire, Gard, France

It is Systoechus.
Regards
Piet

Thank you to put us on the good railway...

If I can eliminate S. ctenopterus with his black hair in the yellow fur, could I propose S. longirostris or is it too much presomptuous ?

An other question with this picture : does the color of the eyes change with sex ou age of the fly ? Because pictures show dark eyes or red eyes as mine.

It is not the wing nervation of Systoechus.

Wing venation would be consistent with Bombylisoma, if I see it well.
Greetings,

Bombylisoma for sure, no shadow of doubt. The trouble is to give a positive ID for the species with only this picture. A more frontal view would be very welcome. If it turns out to be a female, there might be a chance it is B. melanocephalum (bold sexual dimorphism in this species). But again, with only this picture I would keep it as Bombylisoma sp.

Thank you.

I have no other picture but for sure I will be vigilant if I return in this part of the Gard.

I think min Xanthempis both do, in other subgenera the males hunt and females eat.

Nice occur on the Dutch television Paul!

In Dutch some would use it as plural, for 'exemplaar' (exemplar or specimen). Ten exx. then is ten specimens.

Thanks Phil I am thinking exuviae but I can't find the abbrev. so perhaps so
