 I found this Dolichopodidae in my garden, in the west of France. I think it is an Hercostomus sp.. I have tried to use a key I found online (https://alpineentomology.pensoft.net/article/20463/) and it leads me to Hercostomus chetifer (fore tarsomere 2 longer than tarsomeres 3-5 combined).

Is it correct/plausible ?

Thank you !

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.

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
