I found several of these fly puparia in medieval latrines from Copenhagen, Denmark. Anyone know what genus or species it belongs to? About 2 mm long.
Found them in samples with Fannia scalaris, Thoracochaeta zosterae, Ischiolepta pusilla, Muscina stabulans, Limosininae spp., Hydrellia spp. - and others if that helps. It may not have anything to do with faeces as all kinds of organic material was dumped in the latrines.

My first reaction is Phytomyza (Agromyzidae)

Hmm yes - it does resemble Phytomyza chaerophylli although it is not that species. Might not get any closer. Thanks
