I caught this in my garden, Menai Bridge, North Wales, 23 Jan. 2013. I'm hoping it is Heteromyza commixta. That is what it comes to using Collin (1943). But if H. atricornis has sneaked onto the British list via Roger Thomason's Shetland photos, I'm not clear how to separate these two. Gorodkov (1988) said male frons anteriorly tapered only slightly: H. atricornis male frons anteriorly tapered gradually: H. rotundicornis & commixta but I'm not sure what this difference would look like. Can anyone help, please? The specimen is in alcohol so the colours are sharper than in life. John Bratton John Bratton attached the following image:  [109.45Kb] |

Four pairs of dorso-centrals, one pair in front of the suture. You'll have to take my word for it.
