Hi folks,
is this Sciomyzidae or Heleomyzidae and if so, can it be determined to genus or species level? the pic was made today in western Belgium.
anyone knows if there is still a key to Sciomyzidae of NW-Europe that is available?
i know there is this reference (in dutch, so that would be easy for me :) ):
Revier, J.M., & V.S. van der Goot, 1989. Slakkendodende vliegen (Sciomyzidae) van Noordwest-Europa. - Wet. Meded. K. Ned. Natuurh. Ver. 191: 1-64
but i haven't found it yet on any internet shop...
any suggestions on literature on Heleomyzidae is welcome too.

This is not Sciomyzidae but Scathophagidae.
Norellia cf. spinipes.

Merci beaucoup Stéphane,
as you see i have to learn a lot bout flies other than the usual syrphids...
is it possible to give a species name, knowing that i have a specimen?
several of these flies where sitting and even ovipositing on Narcissus cultivars in the garden of my parents and according to several internet pages this species is a leaf miner of Narcissus...
is there anything known about host plants of other Norellia species (N. tipularia?)?

Thanks to Joris Menten, I found following paper:
"DeJong, H. (1985). Norellia spinipes (Meigen) in the Netherlands and its distinction from N. tipularia (Fabricius) Diptera: Scathophagidae). Entomologische Berichten 45; 21-23."
this paper gives somes differences between the 2 species + drawings of the genitalia. I have to take a look at the specimen i collected but it seems like N. spinipes is typical for the hostplant Narcissus and N. tipularia (with a more southern distribution) to Leucojum. Pupae of N. tipularia has been found in the Netherlands in bulbs of Leucojum originating from Hungary.
I will check the specimen as soon as possible and then i probably can remove the "cf" out of the title :)
grtz

Well, in fact the specimen i collected is not the same as the one in the pic (hey, i had a small sprint inside & back outside to have collecting equipment...) because the one i collected is a male. The collected male has all features summed up by De Jong for N. spinipes. And even on the pic one can see several features that can confirm the id as N. spinipes. :)

By mentioning my sighting on a belgian nature forum, several other people started to check the Narcissus in their gardens and another person found and collected the species in his garden at Zemst (near Brussels).
