This female was about 11-12 mm. It looks close to T. nobilitata in galley but there are perhaps other species? Photo from Norasundet, Ångermanland, Sweden 62.53N 17.45 E 26 august 2010 Thanks for your help in advance Regards Kurt Holmqvist kurt attached the following image:  [89.83Kb] |

It looks a bit odd for nobilitata, but it can't be handlirschi, since there is only 1 pair of DC. ?? Theo |

Is Thereva plebeja a possibility?

I've now seen a picture of T. plebeja. It's a much darker species, so that seems not to be an option.

also, the date does not agree. But the frontal callus resembles plebeja, so I could see your point Theo |

Thanks to Jan Willem and Theo. I post a crop of one of my pictures. Is it realy only 1 pair of DC? Kurt Holmqvist kurt attached the following image:  [92.86Kb] |

Looks like you are right Kurt. There seem to be two pairs of dorsocentrals. So with the dark halters I would go for Thereva handlirschi afterall. Let's wait what Theo thinks about it.

Right ! So nobilitata is now very unlikely, and handlirschi it could be. Theo |
