Hi everybody,

I Does anyone knows about the repartition of the unique species of the Coenomyidae: Coenomyia ferruginea in Belgium?
Is it widespread?

What is the situation in other countries?

Summarising NW-European data from Van der Goot (1985):
Belgium: rather rare in the hills
Netherlands: south in the province of Limburg and about five other inland localities in woodland area
France
Germany
Denmark (not after 1900)
Poland

These are the most recent data I have here, though there are one or two more recent record from the Netherlands.

Reference: Goot, V.S. van der, 1985. De snavelvliegen (Rhagionidae), roofvliegen (Asildiae) en aanverwante families van Noordwest-Europa. - Wetenschappelijke Mededelingen van de Koninklijke Nederlandse Natuurhistorische Vereniging 171: 1-66.

Hope this gets you on the way for now.

There is a very recent paper by Jens-Hermann Stuke (2004) on the occurrence of Coenomyidae (and some other small families) in Niedersachsen and Bremen, published in Braunschweiger Naturkundliche Schriften 7(1): 137-142.
I have found the species in Belgium once. If you are interested I can look up the date and locality for you.

The species has been caught several times in the Meerdaalwoud and Heverleebos near Leuven (by Frank Vandemeutter and Jorg Lambrechts). I myself have one ex from Elsenborn. Frank also reported the species from the Argonne in France. It appears the species is not terribly rare, but is on the wing for a very short time in June, which explains it apparent rarity.

One thing I was wondering: I never smelled the cheese-smell on the ex in my collection. Does anyone really noticed this smell?

Yes, I have one exemplar from Moravia, Czech Rep., and the smell is really strong, but we dont say "cheese" ratherly some "soup relish" like Maggi http://www.nestle...soning.htm
