Hello! This doesn't quite look right for Tephritis formosa, could it be T. bardanae? 19th August, near Lincoln UK. Janet blowave attached the following image:  [88.42Kb] http://cubits.org... |

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. 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! http://cubits.org... |

... 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! John |

Wow, hard to imagine that John!  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!
