Hallo,
This fly was reared from Deilephila elpenor and emerged recently. There were seven larvae, 6 then succesfully cocooned, and a couple of flies emerged. Location is Karelia, N-W Russia. Looking the keys through I got it ID as Buquetia musca, but I have a lot of doubts nevertheless. I have a fly now, so I can make more photos with some diagnostic features if needed.

P.S. At first I posted this theme in a wrong section of forum with immature stages (http://www.dipter...d_id=75182), so I'll leave there photos of larvae and cocoons, an adult speciemen will be here.

Hi Akai

You doubts are justified. Buquetia is on Papilio only.
This is a Drino. You can nicely see the strong bristle on the base of vein R4+5.
So, we need to work on the genus

* ocellar bristles are totally lacking, is that correct ?
* are there, by any chance, some hairs present on the eye ? I don't see them, but I think they might be present. Check above a white and then a dark sheet of paper as background.


Let me know.

So, if this fits, it is Drino lota, which is the typical Tachinid for this host.
So, that makes sense.

Hallo,
Thanks for answer!
I guess there is no ocelar bristles (but this sample have only 1 postocelar bristle behind ocelli, is it normal?)
Eyes are exactly haired.

Yes, totally Drino lota, as predicted.

please change the title of this thread.


Thanks
