Dear Forum,

I found this fly very close to the small garden pond. Which one is it?

Thanks,


Markus

With these 3 lines on the eyes, it is something else. The eyes are very hairy, Hybomitra ?

Thanks a lot, Axel!

Hybomitra could fit, although, from the information which I found on the internet, I will likely not be able to see sufficiently details on my pictures to come to the species... I see orange basis of the antenna, I see pale-orange side-markings on tergit 1 & 2, and a glimpse of the same color on tergit 3, I see the bright triangle-shaped marks on the center line of the abdomen, it does NOT have orange upper parts of the tibiae... but I can't see the color of the hair on the 2nd tergit.

There's no description of a species that would fit to all characteristics.

Any chance? Or should I keep it a Hybomitra sp.?

Thanks!

Marks

It is a straightforward female Hybomitra bimaculata.

Thanks a lot, Theo!

May I ask, which characteristic is making the decision?
