 Hello,
Unfortunately, I only have a single, poor-quality photo of this long-legged Dolichopodid. Even so, some important features are visible: 6 pairs of dorsocentral bristles (==> genus Liancalus?), the wing venation : the outer cross-vein is not oblique, and the first bend of the discal vein forms an almost right angle and perhaps 4 unequal scutellar bristles ? (as in the genus Orthoceratium).

What conclusions can be drawn from this, please?

Location: Pyrénées-Orientales; altitude: 1,000 m; date: October 2025.

It is sad news. I read him a month ago, as he replied to me about a wrong identification. He was brilliant, as always.

What a piece of sad news to learn about Mr. Chandler's passing, a great loss indeed

I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.

Canada plans to eliminate the Diptera group at the CNC. See post in the News section of the main page.

Pipunculidae from Mongolia! I am looking for specialist who is committed to ID these. There will be a lot of material coming from my expeditions.

Dr Michael von Tschirnhaus, a leading expert on Chloropidae and Agromyzidae, died on 16 September 2025 at the age of 86. He will be greatly missed by the international community. R.I.P.
