 Found on a heap of Honey Fungus (Armillaria) on a stump in my nearby public park on 2 Nov 2014, Ipswich, East Suffolk (TM163450). I think it is a male Crumomyia roserii. Any comment, and especially confirmation of the species, would be very much appreciated.

Best wishes,
Martin

Here is the place I found the fly

 Looking at Brian Pitkin's key to British Sphaerocerids for important characters, here is a close-up of the wing, which suggests Copromyzinae.

 tibiae yellow brown (especially mid and hind tibiae - see hind legs photos and lateral and ventral views above), anepimeron dusted and, as previously illustrated, no hook on male hind 1st tarsomere -> Crumomyia roserii.

Comments, please...

Best wishes,
