Hi,

I know this isn't the easiest of genera for photo-identification, and I wasn't given enough time to get good quality photos. But maybe the experts here still can find enough details to make out which species this is?
It concerns this observation: https://waarnemin...215705747/.
1 Siphona spec. imago, seen
date: 2020-10-14
location: Wageningen - Wageningse Bovenpolder (GE)

photos:





Thanks in advance!

Kind regards,
Rayan Majoor

Hi Rayan, I've tried to use the T&H key on your images and ended up with rossica (but some characters are not clearly to be seen and fauna.eu doesn't report it for the Netherlands):
- epaulette visibly darker than basicosta?
- 2nd antennal segment yellow (base of third, too?)
- 2 strong marginal bristles on tergite 2!
(see https://diptera.i...d_id=88303

All of which is very OK for geniculata
