Could this be Phaonia, perhaps? Photographed today at Leerdam, Netherlands. Thanks in advance! Jan Zwaaneveld attached the following image:  [85.74Kb] http://slamenietd...web-log.nl |

Yes, Phaonia - not sure about the species just yet.

Thank you, Tony! Are there any special parts of the fly you need to see to identify it to species level? I have some more photos of this fly. http://slamenietd...web-log.nl |

Could be, Kahis, you tell me!  Is there any detail I could find in other photos to be sure? Anyway, thanks for your suggestion!

Looking at this more closely, I don't think this is fuscata. Photo 4 clearly shows the scutellum has a reddish-yellow apex, which fuscata should not have. I'm pretty sure it's either tuguriorum or scutellata. Fonseca separates these females as follows: tuguriorum - frons at vertex more than two-fifths head width; jowl below eye about half eye-height; palpi reddish-yellow on basal third. scutellata - frons at vertex only one-third head width; jowl below eye not more than one-third eye-height; palpi usually almost entirely black. If I was pushed on this, I'd say scutellata, but I think the frons is too wide, so we need a big "?" after the name.

Thanks for your explanation, Tony. Since scutellata is not on the Dutch list, tuguriorum seems to be the more obvious candidate. But, as you told me once in another thread, scutellata is widespread and occurs in almost all neighbouring countries, so there seems to be no reason why it should not occur in the Netherlands. I include some detailed photographs of the head of this fly, perhaps they can tell us more about its specific identity?
