A very long-beaked empid. Sorry, don't know what to try to highlight especially. Can anyone help? Phil Porter philporter attached the following image:  [79.16Kb] |

Empis (sens.lat.) but unless you're an empid specialist with an 'instant recognition' factor, a bit difficult to progress I would have thought with the lack of useful detail. Interesting Thereva, by the way. |

Every little helps John, but I haven't got a key for Empidae at the moment Phil |

Collin's book is a brilliant piece of work; recommended if you get the chance to acquire it (not sure how easy that may be these days). |

I think (!) it is Empis livida, but, as said above, not enough details. I like Collin's book a lot, but it is of course a bit old. I guess it is still possible to purchase it, perhaps second hand, but if you need a good key for Empis, rather buy Chvala's key in the Fauna Entomololica Scandinavica. ruud van der weele rvanderweele@gmail.com |

Phil, do the M1 and M2 from the discall cell reach the margin of the wing?

Ruud, No, they both stop short of the margin. Compared to a specimen which Paul Beuk identified as livida on the site a while ago, this has mouthparts a full 60% longer, measured with an engraved lens. John I'll certainly look into finding Collins book. Re. all these references; 'so many books, so little time and money'. I only have about ten specimens and most probably some duplicates among them, so I'm in for all of the outside help I can get! Regards Phil |

Mouth parts consist of soft and hard parts. The soft parts can be extended and can result in a proboscis that appears to be twice as long as one that is not extended. This is Empis livida.
