I am very curious about the identity of this fly, found on my kitchen windowsill (Essex) in the autumn of 2006. It appears to be sf Sarcophaginae, as it has short bristles on the hind coxae, but I have no idea where to look beyond that. It seems very distinctive with its enfuscated venation. The arista is bare and also a rather distinctive shape. The pointed abdominal tip leads me to think it is female. The abdomen is dusted in a tesselated pattern and it has fairly strong dorsal vittae. It is 12 mm.

Hi Susan
Have another look at the hind coxae. It shouldn't have any "proper" bristles posteriorly. This is
Macronychia striginervis. It is a female - that sharp ovipositor is characteristic for this species. Other features to note are the shape of the abdomen (quite narrow at the base) and the suffusion towards the tip of the wings. I have most often found this species as dead specimens on window sills.

Aahh :) A Miltogramminae then. I did check the hind coxae as carefully as I could, but the view is somewhat obscured by spider web and fluff :D I'll go back and try again.
Many thanks for identifying it and your comments - it is quite a striking fly, even in this condition, so I am pleased to know what it is.
