Thread subject: Diptera.info :: next try to launch a Scathophagid

Hi,
This yellow fly was around together with the Dryomyzid of my previous thread - same location, same day, not same species when seen through good spectacles or in big magnification (where is my good eyesight gone?). So is this a Scathophagid, for instance Scathophaga suilla?
Regards, Sundew

This is Scathophaga sp. The fly does not have a black area on its forefemur, which rules out a host of species. The antennae are not dark, which would indicate stercoraria, but at this stage without the key I would leave it there.

EDITED: Sorry for my mistake, I meant to write contraindicate S. stercoraria...

Dear Gabor, thanks for confirming the genus. However, all the Scathophaga stercoraria specimens I've seen were much hairier and also bigger. In the gallery, there are several species with antennae not dark, and the pics of S. suilla look quite similar...

My first though was definitely S. suilla, but that species should not have strong setae on hind femora. If the arista is hairy, that would take us to S. lutaria or S. inquinata.

No chance to see hairs or not on the aristae - I checked all my pics, but this is beyond the limits of my camera! So it is Scathophaga for sure but the species remains nebulous... Well, better than nothing.
Many thanks to all contributors,
Sundew
