Hello!
This doesn't quite look right for Tephritis formosa, could it be T. bardanae?
19th August, near Lincoln UK.

Your initial id was correct, it is T. formosa.
Mind you, females have a much more extensive wingpattern than males, perhaps that made you doubt.

Thanks John. :)
Yes it was the wing pattern which had me doubting, but the lack of a black glossy strip on the scutellum had me wondering too!

... Can you believe I've never noticed that before! Just been looking at some pictures and indeed the majority seem to have, though not all! Not even sure it is a valid character for the species or whether its variable.
Thanks for drawing my attention to it though!

Wow, hard to imagine that John! :D
I find my own ways often to separate one species from another, so not using keys I have probably picked up on features which those who follow keys haven't. ;)
I found a feature to recognise a male from a female Blue-tailed damselfly which nobody has found too! The female has a 'C' shape turned on the side on the tail segment next to the blue band, males have a sort of sideways 'S' shape. Check it out! :D
