Nice
Siphona ... would be good to see the head from the side, showing the ratio of antenna to frons :) Though I am sure you know it's nigh impossible to identify them from photos ;)

Thanks Chris, I'll check what I have (or we should address Nikita who got the specimen).

Hi Black
Marvelous pictures, still, Siphona are very difficult.
This one might be S. mesnili (the epaulette are quite dark, the thorax is vittate, DC 3+3, laterals on syntergite 1&2 present)

Thanks Theo - I still have to check available images (delay caused by my PC crash, now fixed).

Here's a couple of views of the head, maybe these might help.

Hi Black,
Yes, this helps.
It is Siphona ingerae, readily IDed by the relatively (for a Siphona) long pulvilli. Could have seen that before, the head shot with the broad jowls put me on the right track.
Marvelous pics,
Theo

Many thanks Theo. This applies to the first fly, right? Could you please tell are these two of the same sp.?

Quite likely (the same species)

Black, I always looked at your photos with admiration. You should publish the first(?) diptera coffee table book B)

Thanks crex - I would still reserve the right to produce something even more ponderable one day :) ...

I'm not sure whether it's the same species...

Certainly a
Siphona sp., but you knew that already. I just see the common species here, like
S.geniculata (which coincidentally has been out in good numbers
very early in England) and species like S.ingerae are but a dream! ;)

Thanks Chris - do you know anything about host records of
S. ingerae?

Most Siphona hosts are found in Lepidoptera, only geniculata and some others changed to Tipulidae.
