Unfortunately I have no idea. I have specimen of all (succesful caught) photo flies in ethanol. To send them to an expert the family should be the minimum presupposition. Any suggestions? Complete names are very welcome too Wink Best regards Frank

What about size?

Maybe a Ranunculus petal is a good scale?...

Hi Frank.
The only idea I have is female of Sepedon sphegea, Sciomyzidae.

First thought: Psiliidae.

I'm sorry, of course, Psilidae.

c.f. Loxocera
Robert
Basal position of arista a giveaway for Psilidae? and abdomen projecting beyond wings perhaps?
Is this ever so for Sciomyzidae which was my first guess too.

I wish it was Wink. The head shape is a major part of the Psilid habitus.

As in this Francis Walker drawing of Loxocera albiseta http://delta-intk...psili3.jpg showing the receding face. But do Sciomyzidae ever have a basal arista?
Rainy here today. Is your dry summer over?

Slainte (Cheers) Robert

Thank you very much for your comments.
Knowing the family, it was possible to ask Matthias Buck, Canada, for his opinion: "female of Loxocera aristata or maculata". He gave me some more hints to divide the species. Under the microscope I found all characteristics of Loxocera aristata. Best regards Frank

Hmm, maybe you have other information, but I have my doubts here. To my knowledge, both L. aristata and L. maculata are at least partly yellowish brown on thorax, head, or even abdomen. Moreover, it appears to me that the third antennal segment is shorter than costomary for those species, but that may be perspective. I think I will dig into my books to see if I can find out a little more over the weekend.

Have a look on this photo section, Paul. It shows some of the characteristics for aristata. The abdomen ist completely black.

The species I call aristata.

Sorry about the crappy quality, it's a quick shot. I don't think Frank's fly is conspecific.

LoL, with this I am certain it is not conspecific.
