 Hello,
This Dolichopodid was photographed in the Roussillon Plain (southern France) in a riparian forest (altitude 55 m). With its long, seemingly plumose aristae, it resembles the genus *Poecilobothrus*. However, given its entirely yellow antennae, I cannot determine which species it might be.

 I'd say Hercostomus.

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

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.

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.
