Truncate oviscapt suggests Scaptomyza flava but I can't see the tiny seta between posterior reclinate orbital and medial vertical setae which flava should have according to Fauna Ent. Scand.

I should have said - it is in alcohol so probably looks darker than it would if dry. Even so, it looks very black for a species called flava. |

Check if there is a minute setae present between the posterior reclinate seta on the frons and the vertical seta. If it is there, it should be flava, which does fit the apparent shape of the ovipositor. However, pictures can be deceiving...

Thanks. I'll have another look, but as I said in the second caption, I couldn't see that seta. But the truncate ovipositor is genuine, not a trick of the angle. John |

I re-examined the specimen, this time dry. I couldn't see a seta on the left side but there appear to be two in the right place on the right side of the head, but they are so small as to be at the limit of my microscope's definition - attached.

I also took another picture of the ovipositor. Is this one convincing, please? John John Bratton attached the following image:  [53.79Kb] |

In flava they are supposed to be very small.

OK, I'll call it flava then. Thanks very much. John |
