Tephritid
I DO KNOW already that the last two images here depict Tephritis formosa. (They are here purely for comparison). The first two however look to me to be perhaps a different species as the wings are much less heavily marked.
The two images of my unkown species are of a specimen which came to my garden moth trap light in Clifton, Beds on 22 Aug 2010, so no food plant as a guide to identification!
Any suggestions will be greatly appreciated
Many thanks
Alan

Re: Tephritid
Try Tephritis hyoscyami female.

Re: Tephritid
Very many thanks Malcolm. I had thought that the wing markings fitted T. hyoscyami but was 'persuaded' against it when I looked at the images of that species on the Dipter Info website where the specimens depicted seemed to have very different head and eye colours.

Re: Tephritid
I have looked at the Diptera info images and they look very similar to your specimen to me. You must always be aware that the colour detail in photographs depends very much on the lighting conditions that existed when the picture was taken. Diptera eye colours particularly can be strongly affected by refraction within the eye and the angle of the incident light. I don't believe that there is anoher species recorded from UK with a
similar wing pattern - I may be wrong.

Re: Tephritid
I am sorry Malcolm. I certainly didnt want to imply that I doubted you and I am certain you are correct. I was only accounting for my own inadequacies as a beginner! I had already labelled my images as T. hyoscyami. I fully take your point about lighting and images.
Many thanks

Re: Tephritid
The first two are Tephritis hyoscyami, the last two are T. formosa.
