Identification help - Chyromyidae?

Submitted by Cathy_B on

Hi All,

Decided to use the lockdown period to try something new and venture a little more in to the world of Diptera. I've used keys to get this down to Chyromyidae but if I'm wrong I'd be very grateful if you could flag it (and let me know where I might have strayed). 

Many thanks in advance,

Cathy B

Hi Cathy. First thing to note is how bristly the legs are - this suggests it may not be an acalypterate. Looking at the top of the thorax - there is a well-marked suture running across in front of the wing bases, so this indicates it is a calypterate fly (includes muscids, tachinids, etc.). Hopefully you will now be able to key this to Scathophagidae and use Stuart Ball's excellent key to get it to species.

I had a go at keying this out with Stuart's key and I've ended up at Scatophaga furcata.

Recorded on a footpath near Leeds, W. Yorks.

What do you think?

 

Many thanks,
