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. Edited by caliprobola on 26-03-2009 12:19

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 pieter

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.
