Image recognition points to Helina depuncta, but she has 4 dorsal centrals.

I think it's a female Helina impuncta - but not all relevant characters are visible.

Hi Eric,

Thanks for your response, it is much appreciated. What would be the relevant characters here? I have some more pictures, but of poor quality.

p.s. The sighting was on September 15th in the east of the Netherlands.

Hi Pieter, a higher resolution of the head on this photo could help to have a better look at the arista's hairs. And lateral views could be useful , too, to see the bristles of the legs - especially the tibiae!

Hi Eric, I think this is the best I can do.

Thanks for the images - I think we can now call it female Helina impuncta:
- aristal hairs smaller
- (3 or) 4 dorsocentrals
- 1 pair of elongated presuturals acrostichals
- fore femur yellow
- transverse wing veins shaded...
