Peripsocus milleri - female hiding
Set of images of the first population of this species to be properly identified for the Netherlands in a garden in Kampen (thanks to Peter Kuijper posting them on waarneming.nl).
It has been found on many more locations since and I would presume it to not even be scarce/rare as some older images also seem to show this species, but these were the first to be identified with certainty :o)
Peripsocus milleri is a species of Psocoptera from Peripsocidae family.
