This smaller true bug was resting on Dame’s rockets. It is Closterotomus trivialis (det. GerardL), a very rare species! 
She occurs in southern parts of Europe and is an introduced species here in the Netherlands, where it was first observed in 1998 (source: Nederlands soortenregister) .
A rather nice find.
The rarity of the species has been changed to uncommon .
