BTW, the little mating "dance" performed by the male is quite fascinating to watch. I took the following shot of the same couple a few seconds before the photo above (flash in strobe mode @30Hz during 1/10s => 3 exposures):

Note how the male reaches out to show the female his black tarsi-ornaments!

Another side note: If you've ever tried shooting these flies using pre-flash ttl-metering you know that you will end upp with mostly empty frames since their reaction time is so fast they manage to escape in the short span between pre- and actual flash. While slightly frustrating I've found this to be quite impressive. So the reason I had the flash in repeating mode was to try to capture these blazing take offs. This seems to be the typical take off pattern (50Hz strobe ? you do the math!):


Best regards,

Fantastico!:):D

Thank you Nikita and Nigel!

Would you say <i>N. quadrifasciata</i> is correct or is it hard to tell from these photos?

Cheers!

Yes, This Doli is Neurigona quadrifasciata. Demonstration of ornamented tarsi to female is very specific to this species. I saw Pogonin's film with the species mating.

Splendid, that's good to know! Thank you Igor!
