 Hi Robert
This is Scatella tenuicosta. The shape of the distal spot in the wing is distinctive.

 I am sure it is tenuicosta, and I am sure it has been found in The Netherlands before, even if no-one has recognised it! Grin

 Hello, me again..

It would be nice if Paul or any other specialist (for the Netherlands) can confirm this?! or deny it!?

It is not Scatella stagnalis?, that one is on the Dutch Specielist.

Robert,

 Hi Robert
I would be very surprised if tenuicosta does not occur in every country in Europe! This photo is tenuicosta for sure, but I'll be happy to examine any Scatella specimens from the Netherlands, so that Paul has a specimen-based record to add it to the official list. Many entomologists have assumed that any small anonymous Scatella is stagnalis, but often they have confused this species with tenuicosta.

 Here in Finland both species occur, but S. tenuicosta is everywhere, S. stagnalis is by no means rare but clearly less common than S. tenuicosta.

 Well, maybe tenuicosta does occur in the Netherlands, but if it does, no-one ever bothered to report it under that name.
