Goodmorning all,

Two weeks ago I visited the area of the "Haaksbergerveen", one of the last boglands in the Netherlands. At the edge of a half natural grassland, I discovered this female Orthonevra spec. I can´t figure out which species this is.

There are five Orthonevra´s registered for the Netherlands being O. brevicornis, O. geniculata, O. intermedia, O. nobilis & O. plumbago.

I skipped O. intermedia of my list because it has black yellow legs. Also skipped O. plumbago because over the last ten years it has only been reported once in the outher south of our country.

So I narrowed it down to three. Unfortunately I can´t find a good key to tell which of those three I´m dealing with.

Any suggestions?

Recently learned that this might not be an Orthonevra spec., but probably a Chrysogaster virescens.

I was on the wrong track.
